Friday seems like a good day to see if I can build #i915 drivers into my #arm64 kernel. #nativecontext #testing
#i915
Finally got my hardware brightness buttons to work in #BunsenLabs.
1. With root permission, append this string:
acpi_backlight=native
Between the quotes in the line:
GRUB_CMDLINE_DEFAULT=" "
Which is found in the file:
/etc/default/grub
2. Run in terminal:
sudo update grub
3. Reboot
4. Use hardware backlight keys as normal.
This took me over a week of scorched retinae to unearth. Now i post it here.

Further testing @elementary I am very happy I eventually could fix the annoying "hanging screen" bug, which was due to a bug of the #i915 graphics driver. Now the whole experience is a lot better thanks to the great hint of @mikael I only read by chance.

Now I hope the remaining glitches of the very important #AppCenter and #SoftwareUpdates parts are fixed before release of #OS8, because they don't seem stable enough to me right now.
@yngmar I have (had?)the #i915 “random” freezing issue in #Fedora, on my old x260, but no need to disable speedstep. Just turn off Panel Self Refresh, and that should be it. Add `i915.enable_psr=0` to your kernel settings in Grub as per https://bbs.archlinux.org/viewtopic.php?id=246841&p=2 .
This is the source for #intel #i915 #sriov support using #dkms . Just wish support was in the OOTB kernels - not yet.
Even though the host is seemingly working, it's a bit fragile as will need rebuilding for each kernel update (pinned for now)
Anyone gone through this with the #n100 ? Surely there must be others?
Prior to this I tried full GPU passthrough (ie full device passthrough, not virtual gpu) , but couldn't get it to work reliably.
I don’t really understand the cause and effect here but I finally got rid of “GPU HANG” issue with #i915, i.e.
Jul 02 21:20:50 suppilovahvero kernel: i915 0000:03:00.0: [drm] GPU HANG: ecode 12:1:84dfd7f7, in ChaosGate.exe >
Jul 02 21:20:50 suppilovahvero kernel: i915 0000:03:00.0: [drm] ChaosGate.exe[40919] context reset due to GPU ha>
I did the following:
- Teared my machine into parts.
- Cleaned up everything
- Put some new cooling paste.
- Bought and switched a new PSU.
- Created
/etc/modprobe.d/i915.confand runsudo dracut --force(in Fedora).
The contents of /etc/modprobe.d/i915.conf are the following:
options i915 enable_guc=3
options i915 enable_fbc=1
I put these there because I found multiple forum posts etc. where this was the suggested solution but obviously I have zero idea what they’re doing 🤷 I’ve played Chaos Gate as a test without hangs, and it used to hang within just few minutes.
It is still a bit weird that #Fedora 40 with its default settings gives such crap results on Intel Arc A770.
Can someone tell me, why #i915 fails with #DRM issues, and starts with a black screen after #Grub - sometimes? Sending the system to sleep (standby) and waking resolves the black-screen.

Ruling out hardware failure, because:
- Leap 15.5 didn't have this issue (5.14 kernel).
- Leap 15.6 started having this issue (6.4 kernel).
- Fedora 40 didn't have this issue (6.8, I guess?)
When I force #AV1 on #Youtube, Firefox doesn't play the video (youtube says it's not supported). And yet, AV1 on Firefox's settings is ON, hardware acceleration in general is ON, and vainfo says that AV1 is supported by my #Intel #A310 card (#i915 driver), and yet youtube doesn't work with #Firefox in conjunction to AV1. VP9/h.264 do work, but I wanted AV1 (h264ify didn't help btw). #Debian Testing here, with Firefox-ESR 115.19.9esr. Any clues?

See this pull request for more details on all of the i915 driver changes submitted for the week....
i mean i know this won't get scraped by google but just in case: if you're on #Linux and your #IntelGraphics card with the #i915 driver suddenly shows a blank screen, and the #sysfs #backlight class shows actual_brightness=0 no matter what: just downgrade ur kernel. lol
guess i will be on lts for a while?
The #i915 driver fails with a "failed to add i915 component master (-19)". Never seen that before. Unsure if related to the boot issue.
(It might have to do with DisplayPort communication but that's not in use. I read some something about tweaking BIOS but I do not have that setting. 😁
Meanwhile upgrading to #Kubuntu 20.04 LTS, perhaps the more recent kernel deals with this situation better. If not, after that I will install 22.04 LTS and perhaps *that* will. 😄 🤞
(Else just use 'nomodeset'.)
#intel #shit #i915 #linux #?
https://gitlab.freedesktop.org/drm/intel/-/issues/2010#note_714940 how should i answer this vigorous Intel representative?
I used to have OOM problems when attaching an external #LG 27UD68p-B monitor to my #Dell #XP15 #linux #laptop, but latest #drm #intel #i915 kernel changes (on drm-tip in git) _seem_ to have fixed this issue!
