It's almost plug and play. and win10 doesn't care if you don't register it (Though you may have to use a networking trick to avoid creating a Microsoft account)

Those seem kind of hosed up. The Windows boot entry is the only one I'd consider properly set up. It lists a GPT formatted ESP partition including the file used, and MS put it into a vendor folder. If that Linux install was properly set up it would list another file in that same ESP in a vendor folder for your distro. Pretty much all EFI native distros (i.e. all current ones) will automatically do this on install. Instead, it lists an 850 Evo in that first slot in the boot order but it's BIOS boot, which I don't think any distro installer does without screaming at you if they detect GPT. Note that the entry being there does not mean that it points at a functioning or even existing disk. It's just an entry in the list of boot entries. And it should be further noted that BIOS booting is a little nuts because it just checks for a certain byte sequence and then literally jumps execution into the start of the disk. I'd do an fsck of the partitions on that SSD but with the -n flag so it doesn't modify data. If it comes clear, post some actual error messages and perhaps do a grub install on that disk (which on BIOS systems writes raw code to the beginning of the disk and is, as I said, hosed up). Save your data and do a clean EFI install (change partition to GPT etc). If you try to grub-install into that SSD, what happens? FWIW, here's a working dual-boot EFI-based system where I kept ESPs separate and installed grub into the fallback path due to firmware bugs. code:For the VM, I'd download the red hat signed set of virtio drivers for Windows (as iso): https://docs.fedoraproject.org/en-US/quick-docs/creating-windows-virtual-machines-using-virtio-drivers/index.html I'd add a "Virtio SCSI" adapter to the VM (I don't think the default template does it) and set the virtual disk to SCSI with "discard mode" set to "unmap". The NIC can also be set to virtio. Add another CD drive as well and boot Windows Setup with the virtio iso added. You should then be able to "have disk" and load the virtio driver during setup. Once installed you can use the combi installer on the iso to install the other drivers. That gives you trim support for the virtual disk passed through from VM to hypervisor, fast networking, and well working display output.

Well, okay. All partitions on my SSD came back clean, so I mounted my EFI partition (/dev/sda2 in this case) and did grub-install and it... worked? "Manjaro" showed up as an option in my motherboard boot tools and it loaded GRUB. I'm... not sure why that worked now but not before. Anyway, it's properly booting GRUB now. Thank you! I'm probably eventually going to wipe everything anyway, but for now I can keep using my computer as I have, though I'm still going to try setting up a Windows VM on my Linux install so I don't have to boot into Windows (unless of course some game comes out I really want to play that I can't get working with Proton or WINE!)

If you go through the effort of putting windows in a VM be aware that some anti-cheat systems check for the presence of a VM, some of them will ban you for using windows in a VM. The same goes for some games that work perfectly in wine/proton. For example, Destiny 2 will ban you if you are detected to be running in wine. The list is rather small but you should do some simple googling before abandoning windows in its entirety.

You aren't going to play any 3d games in a VM without loving around with passing through a raw dedicated GPU anyway, and at that point you might as well dual boot because that's fiddly and annoying to set up and maintain.

Jails in FreeBSD originally (though now less-so with the security.jail.jailed sysctl, plus the lack of access to /dev/mem and other kernel stuff), as well as the capabilities-based Capsicum (which is being applied to Firefox like it was to Chromium before Google decided to implement their own sandboxing) are meant to be forms of oblivious sandboxing. I would assume Linux has something similar, possibly NIH'd, though I can't think of what it might be right now.

Honestly it's not really that bad anymore unless you're trying to squeek out every gnat's rear end of performance. There's pretty easy guides. Hell it's probably simpler than trying to setup pulse on your main computer. It did used to be an archaic hellscape to get working but it's not so bad. virsh even helps (some)

mystes posted:I wouldn't necessarily recommend gpu passthrough over using two computers but dual booting is terrible. That seems like a weirdly harsh judgement. I've dual-booted my main desktop for like 20 years now and there are a lot of upsides to it. It is more problematic when having to use a single drive for both, but even on the laptops I've owned I still tended to set up dual-boots. On a decent desktop it is still my preferred setup, although over the years my Windows installs has moved and more to just being used for gaming.

It is even more simple than that, wine has an added system call for applications to check for the wine version running. Any anti-cheat system can simply call that system call and if an exception is not generated it knows you are on wine. There is an open bug for it but the wine developers have stated that they will not get into the arms race of trying to hide wine from applications.

Edit: A different topic but related to wine: Apparently wine almost has working wpf support now. You need to copy a couple dlls that won't compile natively right now but it seems like the open source wpf release plus the wine directx code is actually enough that it should be possible to get everything working with open source code. This made me wonder if it would be possible to use stuff from wine to get wpf working on .net core on Linux and I found this page: https://ccifra.github.io/PortingWPFAppsToLinux/Overview.html Right now he's using windows .net core running under wine, but he suggests at the end that it should be possible to use Linux .net core with winelib which actually might not be that bad. mystes fucked around with this message at 11:27 on May 4, 2020 |

It's funny because when they opened source WPF everyone was like "oh but that won't help get WPF support on linux because you don't have all the low level windows apis to support it," but wine apparently does actually have that already. Also I don't know even know why I want to be able to use WPF from .net core on linux because i hate WPF, but it would be cool. Actually now I wonder if anyone's tried to use winelib to get winforms support on .net core on linux? Winelib normally sounds like it's way more trouble than its worth (probably significantly more trouble than just porting programs), but if you could just use the graphics parts it might actually be almost decent.

Is there any way to control the order in which devices are presented to applications? E.g. some games see my joystick when it's plugged in before my gamepad and only use that effectively making the gamepad useless. Unplugging the joystick fixes it but is annoying when I'm downstairs on the couch.

Also I just tried to do a system upgrade using LVM snapshots which I normally do and it works fine; however this time my snapshot seems to have disappeared and it partially merged? After the upgrade to F32 things were fine and I rebooted a few times like I normally do to make sure everything is working fine before trying to merge my snapshot. What is the best way to recover from a hosed up merge and what things should I look out for? I ran xfs_repair and reported doing some stuff and the sizes reported by vgs and lvs are consistent but now I'm super paranoid about the system. The upgraded kernel fails to boot and it's missing a bunch of poo poo e.g. all of the /lib/modules/ however my older kernels still work fine, it's quite bizarre...

This sounds like the new kernel rpm did not install correctly. Was the update interrupted or did it run out of disk space or something? Try an rpm verify or just reinstall the packages (kernel, kernel-core, kernel-modules, etc).

Do LVM snapshots even quiesce the fs on top when you create one? XFS is journaled but I still don't like to take my chances during a rollback. Anyway, as far as I know you aren't going to unmerge a snapshot. If it's not there and it isn't merging in the background you may be hosed. It does sound really weird though, that's not a thing I've ever heard of. I have heard of weird things happening if you run out of free space for the delta volume though. That scenario always sounded utterly terrifying to me. I'm sorry I can't be of much help.

I use rsnapshot which creates temporary LVM snapshots every 15 minutes and I've never had a snapshot end up with the FS corrupted, it must ensure that the FS is at a good point.

After some more investigation it looks like it actually got dropped, though I didn't see anything in the logs; however update still had F32 images under /boot which was confusing and part of the problem (of me figuring out what the hell happened). I think I've cleaned it up and am in a consistent state so trying to upgrade again we'll see if we choke again. quote:Do LVM snapshots even quiesce the fs on top when you create one? XFS is journaled but I still don't like to take my chances during a rollback. Can you ELI5? I'm not super familiar with filesystems details so I like to learn this stuff when I can but it's arcane to read a man page about it and understand what it means. Like I understand the very high level basics of a journaling filesystem and that it keeps transactions on record until it's fully commited and flushed from the system but not in terms of most practical cases (e.g. this one and rolling poo poo back and how/why that would affect LVM).

If the snapshot just happened whenever, the filesystem might be in the middle of making changes. With a journaling filesystem, that isn't a huge problem because the journal ensures you can go backwards in the journal until you are at a good spot. Rather than a full fsck like you might need with an fs like ext2

Mr. Crow posted:Can you ELI5? Let's say the package manager is installing updates. You wait for it to finish, then pull a snapshot. However, the file system had been holding some changes back in cache before flushing to disk. At the time of the snapshot the fs is inconsistent. If LVM quiesces the fs, it would send some kind of signal to tell the fs to flush all its changes and block new ones until the snapshot is done. If it doesn't, then once you return to the old point in time you'll have to fsck because the fs is dirty. You will lose data. I have absolutely no idea if LVM snapshots force this flush properly. Generally speaking though, you can't return to snapshots of mounted file systems without putting data at risk unless the fs itself supports snapshots. The LVM docs just say that "some filesystems do this automatically", which is not helpful. Btw., I found this in the docs: quote:If the snapshot logical volume becomes full it will be dropped (become unusable) Yikes. ZFS will ENOSPC, but LVM just shits itself?

Actually I'm just an idiot and too used to thinking in terms of git. When you merge a snapshot you're actually reverting back to the previous state and I switched the methodology in my head so I reverted (merged) when I should have dropped. Pebkac

What would be considered best practice for handling logs for user crons? I've got a youtube-dl job automated via cron that currently just dumps a formatted output to a file in ~/bin where the script being called lives. Tail-ing the output file certainly works well enough, but I was curious if there may be a reason to be redirecting output of the script to /var/log or something vs the way I'm doing it now.

Letting your cron print to stdout will save the output to your cron facility's log location, probably in journald? It's one of those things where there is a sane default behavior, but you don't know which one it is because there are lots of options for running crons

Sidestepping your question, but instead of using cron, make a systemd unit that has a timer, provided you're using systemd. If you use systemd to run a cron daemon such as crony, the logs for all cron tasks will probably be in journald for crony's systemd unit. Whereas if you make a systemd unit for each task, you get separate logging for each task in the journal (and much better control of its execution.)

What am I missing?.... I have two machines at home, Win10 and Kubuntu. The latter has a samba share setup. Works fine with my main account and has done for ages. I have a laptop I only want access to one area so I've: Created a new linux account. Group permissions correct on folder and can ssh in as the new account and access the required directory Done a 'smbpasswd -a' to add the user to Samba. It shows up in pdbedit -L -v I've modified smb.conf and added the account to the 'valid users' Restarted smbd and nmdb Yet I get a NT_STATUS_ACCESS_DENIED error for the new user account. Primary account still works. fakedit: I've discovered if I rename the share in smb.conf, ie [OldName] to [NewName] and restart Samba, it works for both accounts. If I go back to [OldName], it stops working for the new user again. Is there some weird permission cache somewhere?
