21:20PaulJ1: I have an old computer with a nvidia GT215 [GeForce GT 240], therefore I need the nvidia-legacy-340xx-driver. I installed bullseye. nvidia-detect responds: driver available only up to buster. So, there is no chance to resolve this problem?
21:20imirkin: which problem are you attempting to resolve?
21:45PaulJ1: @imirkin: When I start bullseye the screen is black
21:51imirkin: what is bullseye?
21:52imirkin: oh, debian release
21:52imirkin: do you know what kernel it ships?
21:53imirkin: there was a semi-recent issue affecting tesla chips, not sure if GT215 would be covered under that
21:53imirkin: (i mean, GT215 is definitely tesla, not sure if it was affected by that problem though)
21:53imirkin: karolherbst: do you know offhand?
21:54imirkin: PaulJ1: please supply a dmesg for a problematic boot
21:54imirkin: that is likely to hold clues
21:56karolherbst: imirkin: I don't think so... but it could be.. depends on if gt215 used the nv50 code or its own
21:57karolherbst: ehh fifo it was
21:57karolherbst: imirkin: ahh yeah.. should be affected as well
21:58karolherbst: everything using g84_fifo_new was
21:59PaulJ1: @karolherbst: so, what is the consequence?
22:00karolherbst: PaulJ1: nothing you need to be concered about
22:00karolherbst: it got broken it 5.12
22:00karolherbst: and the fix got added to stable kernel trees
22:01karolherbst: you could run into a different issue we might also have fixed
22:01KitsuWhooa: What does this have to do with the proprietary nvidia driver?
22:01karolherbst: KitsuWhooa: nvidia droped support so user has to use nouveau
22:01PaulJ1: well, nouveau driver gives me a black screen
22:02karolherbst: PaulJ1: it could also be that imirkin was refering to a different isssue... and I think there was another one we recently fixed.. let me check
22:02KitsuWhooa: Ah, I misread, sorry
22:03karolherbst: PaulJ1: sooo.. debian does have mainline kernel builds, but... debian says "we don't want users to be able to use them in a simple way, so if you know what you do, download those deb files and install them"... or you can just build it yourself and see if it persist with 5.15 or 5.16
22:03karolherbst: 5.14 or 5.15
22:03karolherbst: (not kidding about that debian quote thing)
22:03karolherbst: (or it was ubunut)
22:04PaulJ1: I see, so my way out is to build nvidia-legacy-340xx-driver, right?
22:05karolherbst: well.. chances are the issue is fixed, we had to deal with some of the issues and I know that at least all my Tesla GPUs work
22:05karolherbst: it's just painful to try out newer kernels with debian sadly...
22:06KitsuWhooa: PaulJ1: chances are it's incompatible, and because it's legacy, nvidia probably won't update it, so you'll need to either downgrade or get nouveau to work
22:07KitsuWhooa: Maybe you can find someone who patched it and got it working
22:07karolherbst: it could be that the 340xx is out of support
22:07PaulJ1: I see, thank you anyway
22:08karolherbst: how is the kernel package called in debian-sid?
22:08karolherbst: KitsuWhooa: https://packages.debian.org/search?suite=sid&arch=any&searchon=names&keywords=linux-image
22:08PaulJ1: but, why is it not working with nouveau?
22:08KitsuWhooa: This suggests installing a deb from experimental https://wiki.debian.org/HowToUpgradeKernel
22:08karolherbst: PaulJ1: because your kernel might be old
22:09karolherbst: try the 5.14 backported one
22:09karolherbst: bullseye does package those as it seems
22:09KitsuWhooa: karolherbst: https://packages.debian.org/search?suite=sid§ion=all&arch=any&searchon=names&keywords=linux-image-5.14
22:09KitsuWhooa: and this still brings up a lot of results
22:09karolherbst: KitsuWhooa: ehh...
22:09karolherbst: why is there search stuff broken?
22:09PaulJ1: my kernel version: 5.14.0-3-amd64
22:10karolherbst: then the fix might actually help
22:10karolherbst: I thought you are on 5.10
22:10karolherbst: PaulJ1: it's 5.14.9 or what kenrel version is it?
22:11PaulJ1: uname -r returns: 5.14.0-3-amd64
22:11karolherbst: what does "dmesg| head" say?
22:11karolherbst: (debian kernel versioning is so useless...)
22:12karolherbst: v5.14.14 does contain the fix
22:12karolherbst: if your kernel is older you might run into random weird issues
22:13karolherbst: we know it broke suspend/resume and I got weirdo artefacts on the screen
22:13karolherbst: too old then
22:13karolherbst: the patch got pushed like this month, so distributions might take a while
22:13PaulJ1: aaah, I see
22:13PaulJ1: so I should change my source?
22:14karolherbst: you mean when building it yourself? yeah.. using 5.14.14 _could_ fix your bug, if not you might hit a new one we are not aware
22:15KitsuWhooa: If you can, maybe downgrade to 5.10, that might fix it
22:15karolherbst: ahh yeah.. that might be a simplier thing
22:15KitsuWhooa: It should be available https://packages.debian.org/search?suite=bullseye&arch=amd64&searchon=names&keywords=linux-image-5.10
22:15karolherbst: if you can verify it works with 5.10 we can be sure that 5.14.14 will fix it once it's available
22:16PaulJ1: ok, I'll try a downgrade
22:17KitsuWhooa: If you somehow forced the nvidia installer to run, you'll need to undo whatever it did, as that could also cause a lot of trouble (and prevent nouveau from loading)
22:17karolherbst: KitsuWhooa: yeah.. but normally the screen wouldn't become black if nouveau doesn't load
22:18KitsuWhooa: that's true, actually, yeah
22:18KitsuWhooa: well, if the nvidia kernel driver (somehow) compiled, maybe the DM tries to use incompatible userspace libraries and fails
22:18KitsuWhooa: that could result in a black screen
22:19karolherbst: ohh, could be
22:19KitsuWhooa: I really doubt the glue would still compile though
22:19karolherbst: kind of depends on what nvidia actually tries to do, but normally if you are sane and only use packages (and not installers directly) it should be fairly safe once removed
22:19PaulJ1: would it help if if dump the dmesg in a file and upload it so you can have a look?
22:20PaulJ1: is there something I should hide? I'm not so experienced...
22:20karolherbst: kind of depends on what's going on actually
22:21karolherbst: inside dmesg no
22:26PaulJ1: what is the usual place to dump it online?
22:27karolherbst: PaulJ1: ehh.. I ususalle search for "pastebin" and use whatever is not annoying
22:27karolherbst: or gist
22:27KitsuWhooa: you can use https://paste.debian.net/ or any pastebin service
22:35KitsuWhooa: I don't see anything immediately obvious that goes wrong... Maybe karolherbst can tell
22:40karolherbst: yeah mhh
22:40karolherbst: at least the kernel isn't complaining
22:41karolherbst: PaulJ1: connection issues?
22:42karolherbst: ahh.. I see the issue :p nvm then
22:42karolherbst: did you try 5.10?
22:43karolherbst: PaulJ1: also.. do you know if it's an X/wayland whatever issue? Mind disabling the login manager and see what happens then?
22:43karolherbst: the nvidia installer messing up the system is another thing which could break everything
22:54karolherbst: PaulJ1: do you know if you are using X? In this case the Xorg log could help
