Well, looks like bug occured again. In drm-tip, and also it occured in version v5.19.5
I realized, that I have also computer with se same(i believe) graphic card, and i do not remember for problem to occur on this pc even once. so I looked for difference in these two computers. I tried these commands to find difference: glxinfo -B lscpu lshw And (from my point of view) interesting difference is: glxinfo: Pc where error does not occures: Version: 22.0.1 Video memory: 3072MB pc where error occures: Version: 22.0.5 Video memory: 15928MB (note, that pc where error does not occures has 8GB ram, and the one where error occures has total 16GB ram.) ie, probably video memory can consume entire ram? But I did not remember setting that, so these have to be default settings, or do not know.) lshw: pc ok: lshw product: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz vendor: Intel Corp. physical id: 1 bus info: cpu@0 version: 6.78.3 size: 2800MHz width: 64 bits pc nok: lshw product: Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz vendor: Intel Corp. physical id: 1 bus info: cpu@0 version: 6.78.3 size: 2700MHz capacity: 2800MHz width: 64 bits there is different "size" value, and pc that does not shows screen shifting misses "capacity". lscpu differs in these two rows: pc ok: lscpu Vulnerability Spec store bypass: Mitigation; Speculative Store Bypass disabled via prctl and seccomp Vulnerability Spectre v1: Mitigation; usercopy/swapgs barriers and __user pointer sanitization Vulnerability Spectre v2: Mitigation; IBRS, IBPB conditional, RSB filling pc nok: lscpu Vulnerability Spec store bypass: Mitigation; Speculative Store Bypass disabled via prctl Vulnerability Spectre v1: Mitigation; usercopy/swapgs barriers and __user pointer sanitization Vulnerability Spectre v2: Mitigation; IBRS, IBPB conditional, RSB filling, PBRSB-eIBRS Not affected Main difference is in seccomp, and PBRSB-eIRBS Not affected... have no idea if it is something interesting. anyway, full list of response commands is in attachment. I may try to downgrade from version 22.0.5 to 22.0.1 but i am not sure what exactly to downgrade. ** Attachment added: "bugrep8.9.zip" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1987711/+attachment/5614739/+files/bugrep8.9.zip -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1987711 Title: [i915] Ubuntu display get shifted after some time. Status in linux package in Ubuntu: Incomplete Bug description: It is continuation of this bug: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1986583 where advised fix was applied. Summay: After ubuntu is turned on, after some time screen gets shifted to side. (and starts to overlap) I setup webcamera to record screen, and video below shows what it looked like. after fix were applied. www.ms.mff.cuni.cz/~krasicei/capture-0231.bug.crop.slow.mp4 (video was cropped, and slowed down 2x) before fix was applied shift looked somehow like this: www.ms.mff.cuni.cz/~krasicei/bug17-50-18-8-2022.c.mp4 (video is also cropped, and slowed down 2x) During shift no one was present on computer. Is there any idea how to enable some more detailed log or something? I probably can pinpoint exact moment in time when shift happened. i tried to read log journalctl, but I found nothing interesting.
