Created attachment 194831 [details] Error log grabbed from my eeePC. I saw this display bug after I upgraded to linux 4.3 on my archlinux. Display is completely useless with my old eeePC using this chipset : 00:02.0 VGA compatible controller: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller (rev 03) But it works on my laptop which is using a "younger" Intel chipset : 00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07) I reported this bug on archlinux bug tracker : https://bugs.archlinux.org/task/46968 And here is the error log related to the bug I got on my eeePC. I hope it is not a duplicate.
Looking at the beginning of error log, and google it to find this discussion. Known bug ? Nov 4 17:00:05 fredo-arch-eeepc kernel: WARNING: CPU: 1 PID: 44 at drivers/gpu/drm/drm_atomic_helper.c:674 drm_atomic_helper_update_legacy_modeset_state+0x26a/0x280 [drm_kms_helper]() https://lkml.org/lkml/2015/11/10/321 Related or not ?
