Another CRT issue I've had: a complete or nearly complete set of video modes for my CRT is available under KDE/X11, and I usually set it to 1600x1200@70 for desktop use. However, 1600x1200 is not available at all under KDE/Wayland (the resolutions go up to 1920x1080, as if it were a cheap LCD), and resolutions over 1024x768 are locked to 60 Hz. Even then, lower resolutions have severely limited refresh rates--1024x768 goes up to 75 Hz under KDE/Wayland but 120 Hz on X11. I have seen some pages on how to force Linux to enable specific video modes but they appear to involve GRUB configuration and kernel parameters, and for all I know the compositor could just ignore them. Is there any other way? E: I am using it with a 13W3 to VGA adapter daisy chained into a VGA to DP adapter Woolie Wool fucked around with this message at 07:00 on Mar 17, 2024 |

Is there any other way? There is another way, but it's to generate a fake EDID and force the kernel to use that, and sounds like even more of a pain. (Secret third way: buy & return VGA adapters until you find one that passes the EDID of the CRT monitor while also not causing new problems.) The root of the problem is that, when connected through a VGA adapter, you aren't getting EDID which is how the monitor tells the PC what specs it can run. So the OS just presents a bunch of default "safe" resolutions and the basic 60hz refresh. On Xorg you can override that easily. On Windows you generally use video drivers to add custom resolutions and then the driver passes those to the OS as "approved" modes. On wayland, KWin and Mutter (gnome) don't have the ability to override modes. Sway does, because sway is made by people who want that type of hyper control.

This is exactly the sort of poo poo I went to Linux to get away from.

We can't have users making custom video modes, they might type in the wwong numbies and get a bwack scween! They'll be scawed!Reading up on EDIDs this looks like it's going to be really annoying.

I've seen people suggesting flashing older versions of your BIOS to be able to access the old functionality to change this, but I've also seen people saying this is a potentially bad idea, as its possible that newer hardware/firmware simply won't support S3 sleep. Well this fixed it for a while but its regressed for (??) reasons. I'm on the verge of giving up and going back to a mac. I close my company-provided macbook at 100% battery, its at 99% when I open it up in the morning. I close this linux thinkpad at 100% and its at 50% in the morning. I've been banging my head against this for a month now. It's a shame that hardware issues continually let me down when I try out linux because in all other respects the experience is a lot nicer, I infinitely prefer KDE to the macOS UI, hate mac keyboards so prefer different laptops, other stuff like terminals are better by default.

Nah, at least for KDE it's more like "sorry we haven't made that function yet". This isn't something that's part of the Wayland protocol or spec, so it's kinda up to each of the compositors to implement it or not. But wishlists don't happen until someone who cares writes the code, and these days it is a very small niche. (I'm assuming you don't want to stick with Xorg because you have a different set of problems from it?) Woolie Wool posted:Reading up on EDIDs this looks like it's going to be really annoying. Do I have to download the kernel source? No, you def don't need to download the kernel source. Do you need to change resolution on the CRT? If not, these instructions should work equally well for KDE as gnome -- it's setting a rez and refresh for the DRM (Direct Rendering Manager). Skip over the bits in that blog about parsing the EDID, you don't have a useful EDID to parse. You are just setting an option in the kernel parameters. It's the same thing as launch options for a normal program, but you put it in GRUB config. code:Then sudo grub-mkconfig -o /boot/grub/grub.cfg to regen your GRUB config, reboot, and the CRT should be set. If you want to have multiple CRT rez & refresh options you need to create a custom EDID file. Then use a launch option to force that EDID to be associated with an output. You still don't need the kernel source, but generating an EDID from scratch seems like a PITA. on reddits people say that the windows program Custom Resolution Utility can export EDIDs, that might be the easiest option.

Yeah I'll definitely have to look into generating an EDID because changing resolutions on the fly is one of the main reasons to even have a CRT at all. Of course this wouldn't have been necessary if video card makers didn't delete the RAMDAC and VGA ports from their cards

System 76 is an all-Linux vendor that uses well-supported hardware that reportedly has great battery life. I get approximately 1% battery loss per sleep-hour on my AMD Framework 13 running Fedora 39 with Sway. I leave 2 x USB C, 1 x USB A and 1 x HDMI modules in it overnight. 1% per hour loss is not the best efficiency, but it's ok if I plan to use the computer the next day. Another thing that makes it bearable is that the computer charges really fast from a charger this small: https://www.amazon.ca/Anker-Charger-Compact-Foldable-MacBook/dp/B09C5RG6KV/ref=sr_1_5 It can also trickle charge off my 18W Pixel charger or 20W iPad charger if I want to go even smaller or lighter. Overall I get around 6 hours of video watching or 9 hours of light use. This is my first real committed desktop Linux experiment and I'm rather pleased with the frequency of bug fixes. In the 5 months that I've had it it's noticeably become better and better to use.

Switching my thinkpad to Linux sleep mode in the bios made a huge difference for me. I lose about 7-10% per night which isn’t great but for picking up and putting it down throughout the day is fine. I can’t compare to windows on this specific machine but I don’t remember much better sleep performance on windows 11 on a laptop once I account for battery size. I also grabbed powertop and let it do its thing and it basically brought my battery life up to what I’d expect from windows. I don’t expect Mac power management because, well, Apple makes the best laptops and can tailor their os to them so they get even better power management out of them.

They disabled "linux" sleep mode (S3 or suspend to ram) in the bios for the recent thinkpad models. I've been told it's being phased out and that it's a bad idea to flash in an older version of the BIOS to try to enable it.

But it was stuff like: sudo iptables -t mangle -A OUTPUT -p tcp --dport 8896 -j MARK --set-mark 1 sudo iptables -t mangle -A OUTPUT -p udp --dport 8896 -j MARK --set-mark 1 added 100 jellyfin to /etc/iproute2/rt_tables And then some more that I have to keep digging in here to remember. drat, I should documented all this when I was doing it.

Unfortunately kubuntu was limited to a kernel before the fix, and from what I read its a bad idea to install a kernel your distro doesn't support. I installed arch linux because I heard its supposed to be the "bleeding edge" distro, and voila. Shut the laptop at 100%, and it was only 97% 8 hours later. So I guess the solution was "install arch"? I'll see if this sticks, I didn't have any browsers or anything running at all when I shut the laptop and will check and see if it makes a difference.

I think if you're OK dealing with dependency hell yourself like the greybeards of yore, you can do what you want - but if you want the package manager to take care of it, you probably should install the kernel provided by your distro's repos. So, I guess package managers happened to Unix? IDK, I'm no expert but my understanding was that kernel update policy is a key defining difference between many common distros. Happy to be educated if it's more complicated than that.

Subjunctive posted:Did you ever try to run the “wrong” kernel on SunOS or HPUX? Lots of poo poo would break and you’d never get support for anything atop it, including Oracle. Well sure, but breaking SunOS was something that all kinds of activities could cause, including, but not limited to, patching the kernel, typing the wrong key in the FORTH-based boot firmware, starting X11R5, or using SunOS. I had a college professor (J) who got mad at another college professor (M) and changed the firmware so that the A key would trigger A1-reset and hard-reboot the machine. So M got into the habit of keeping the letter "a" copied into the X11 paste buffer, and middle-clicked the mouse every time he needed to type the letter "a". None of the students would admit to knowing what the problem was, because he was a clueless jerk, and watching him struggle was funny.

Around that time, I think, someone started trying to do it the other way around - which has the advantage of probably being easier, since I believe most of the FreeBSD userland already gets built for Linux distributions as a package.

Also this kernel version chat made me remember to try a newer kernel on Debian 12 to get AMD p_states going so I went to 6.8.1 and it literally dropped my wall-power usage in half when idling - cores drop to 400mhz now instead of 1800mhz. Worked great for a few hours til I tried to launch a Steam game and of course ZFS is currently broken with that kernel, lol. Edit: Also cool graph porn:  Double-edit: Turns out the "stable" 6.7.10 kernel is what I wanted, AMD p-states and a functional copy_file_range for ZFS.

Also if you don't have any files that match the glob then "*.jpg" expands into "*.jpg". If you're using bash you may want to look into the failglob or nullglob options.
