description |
Filing this with my Kubuntu Focus (kfocus.org) OEM hat on:
[Impact]
We are having screen flickering and glitching issues with some of our hardware upon wake from suspend. We have worked with our ODM to figure out a fix for this. They had reported there were no issues when running Windows on the same hardware. As such, we tested, and found that this issue first began as a regression in kernel 5.0 (did not exist in kernel 4.18 per our tests).
We identified a patch via https://gitlab.freedesktop.org/drm/intel/-/issues/272 in which this has been solved. Per our testing by recompiling the kernel, this completely fixes our hardware issue. As of 4-21, this fix has been merged into the Linux kernel per Timo Aaltonen, and will be included in the kernel in the 5.13 release.
Our hardware ships with Kubuntu 20.04 LTS, which means the 5.13 kernel will not see these machines, at least in the forseeable future. As such, we request that this patch be added to the kernel. Per our testing, this patch is straightforward to add and works flawlessly.
Until this is fixed, we have a whole batch of hardware we cannot sell, so, as an OEM, this is a high priority.
[Test Plan]
* Install Kubuntu on an affected Kubuntu Focus M2 computer (not in the hands of customers at this time)
* Notice screen glitching/flickering after wake-from-suspend.
* Install kernel compiled with the attached patch. Boot from patched kernel.
* Suspend laptop, resume. No glitches.
[Where problems could occur]
* Although this solves the problem for us and has been confirmed to work with the Intel developers that developed this patch, it could cause another display type to have problems. This is unlikely as it has been vetted by Intel and by the mainline Linux kernel developers. |
