New issue by adriangoransson on void-packages repository
https://github.com/void-linux/void-packages/issues/29394
Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
Hi! and apologies if this is nowhere near the correct forum to ask this (where might that be?). I noticed that upon upgrading to Linux5.11 from 5.10 that I could no longer use the maximum resolution of my external monitor. I can confirm that it does work on 5.9 and 5.10 (although for 5.10 it didn't once after a point upgrade so it seems a bit flaky).
### System
* xuname:
`Void 5.11.4_1 x86_64 GenuineIntel uptodate rFFF`
* packages: I don't know what may be the culprit so here's a bunch of them!
`linux5.11-5.11.4_1` (incl. headers)
`linux-firmware-intel-20210208_2`
`intel-media-driver-20.4.5_1`
`xf86-video-intel-2.99.917.20200515_1`
The same configuration works just fine on older kernels: `linux5.10-5.10.22_1` and `linux5.9-5.9.16_1`.
* /proc/cmdline if that is helpful
`BOOT_IMAGE=/boot/vmlinuz-5.11.4_1 root=/dev/mapper/void-root ro loglevel=4 init_on_free=1 rd.lvm.vg=void rd.luks.uuid=<uuid> resume=/dev/void/swap`
### Expected behavior
Using `xrandr`, the full resolution (3840x2160) of my external monitor should be visible.
### Actual behavior
```sh
xrandr
# snip
DP3 connected (normal left inverted right x axis y axis)
2560x1440 59.95
1920x1200 59.88
1920x1080 60.00 60.00 50.00 59.94 24.00 23.98
1920x1080i 60.00 50.00 59.94
# more output modes...
```
### Steps to reproduce the behavior
Boot Linux5.11 and try to set the monitor resolution.
I have a laptop with a Intel Tiger Lake 1165G7 processor with integrated graphics. It is connected to a Dell P2715Q with Displayport over USB-C.

Comment:
Maybe https://gitlab.freedesktop.org/drm/intel/-/issues/3179 ?
I will try to look at the config, but I'm doubtful that's the issue, since it's copied straight from 5.10.

I'm not entirely sure that I understand the issue, but it does look a little suspicious. I'll keep an eye on it, thanks @ericonr!
If there's anything I can do to help, just tell me!

Comment:
You can try to look at dmesg and see if there's anything suspicious, though the definition of "suspicious" here is rather broad.

Sorry for the delay! I tried diffing the 5.10 and 5.11 dmesg but didn't find anything in particular.
Here's a diff if it may help. I've sorted it to avoid identical lines being included just because they appeared in different order.

I am using a DELL U2520D external monitor connected through USB Type-C and I think I am encountering the exact same issue.
With linux5.10 my maximum resolution is 2560x1440 / 60Hz
And with linux5.11 its capped at 2048x1080 / 30Hz and is kind of slow / blurry

Comment:
It tested linux5.12-rc5 and the issue seems fixed. Probably thanked to https://patchwork.kernel.org/project/intel-gfx/list/?series=450261 which will get backported to 5.11 at some point.

Comment:
@marmeladema would you be up to sending a backport request to kernel, if it hasn't been backported yet? Given that fedora backported it locally, idk if they pushed for it in kernel upstream as well :/

Closed issue by adriangoransson on void-packages repository
https://github.com/void-linux/void-packages/issues/29394
Description:
<!-- Don't request update of package. We have a script for that. https://alpha.de.repo.voidlinux.org/void-updates/void-updates.txt . However, a quality pull request may help. -->
Hi! and apologies if this is nowhere near the correct forum to ask this (where might that be?). I noticed that upon upgrading to Linux5.11 from 5.10 that I could no longer use the maximum resolution of my external monitor. I can confirm that it does work on 5.9 and 5.10 (although for 5.10 it didn't once after a point upgrade so it seems a bit flaky).
### System
* xuname:
`Void 5.11.4_1 x86_64 GenuineIntel uptodate rFFF`
* packages: I don't know what may be the culprit so here's a bunch of them!
`linux5.11-5.11.4_1` (incl. headers)
`linux-firmware-intel-20210208_2`
`intel-media-driver-20.4.5_1`
`xf86-video-intel-2.99.917.20200515_1`
The same configuration works just fine on older kernels: `linux5.10-5.10.22_1` and `linux5.9-5.9.16_1`.
* /proc/cmdline if that is helpful
`BOOT_IMAGE=/boot/vmlinuz-5.11.4_1 root=/dev/mapper/void-root ro loglevel=4 init_on_free=1 rd.lvm.vg=void rd.luks.uuid=<uuid> resume=/dev/void/swap`
### Expected behavior
Using `xrandr`, the full resolution (3840x2160) of my external monitor should be visible.
This is how it looks on linux5.10-5.10.22_1.
```sh
xrandr
# snip
DP3 connected primary 3840x2160+0+0 (normal left inverted right x axis y axis) 600mm x 340mm
3840x2160 60.00*+
2560x1440 59.95
1920x1200 59.88
1920x1080 60.00 60.00 50.00 59.94 24.00 23.98
1920x1080i 60.00 50.00 59.94
# more output modes...
```
### Actual behavior
```sh
xrandr
# snip
DP3 connected (normal left inverted right x axis y axis)
2560x1440 59.95
1920x1200 59.88
1920x1080 60.00 60.00 50.00 59.94 24.00 23.98
1920x1080i 60.00 50.00 59.94
# more output modes...
```
### Steps to reproduce the behavior
Boot Linux5.11 and try to set the monitor resolution.
I have a laptop with a Intel Tiger Lake 1165G7 processor with integrated graphics. It is connected to a Dell P2715Q with Displayport over USB-C.

Great! Thanks @marmeladema and @ericonr for your hard work. It's very much appreciated!
I just upgraded linux5.11-5.11.22_1 -> linux5.12-5.12.6_1 and all available modes are shown again.
