hi, could you please add your mesa version?
You can use => glxinfo
And, I think, for devs it would be helpful to provide all possible logs you have (as you mentioned, you saw gnome crashes, provide them too please).
>>I updated the "Intel Iris Plus Graphics 650"
That's for windows 10 on your second drive?
Created attachment 138685 [details] glxinfo output glxinfo has been attached as glxinfo.out. Windows 10 is installed on a completely separate drive that needs to be installed (I'm not dual booting) I have reported 3 different bugs at redhat's bugzilla, all traces, logs are attached to each bug. https://bugzilla.redhat.com/show_bug.cgi?id=1560959 https://bugzilla.redhat.com/show_bug.cgi?id=1561436 https://bugzilla.redhat.com/show_bug.cgi?id=1562448 all of which are duplicates of https://bugzilla.redhat.com/show_bug.cgi?id=1523416 If that's an issue with the refresh frequency, it's more likely to be an issue related to i915. Please try to reproduce the error using drm-tip (https://cgit.freedesktop.org/drm-tip) and kernel parameters drm.debug=0x1e log_buf_len=4M, and if the problem persists attach the full dmesg from boot. Hi could you give me more detail instructions. Thanks Dan Please just start off with your current kernel and drm.debug=0x1e log_buf_len=4M parameters, and attach dmesg. Created attachment 142950 [details]
dmesg after kernel parameters added to grub
The attached dmesg.out was generated after the grub file update below and a reboot
drm.debug=0x1e
log_buf_len=4M
GRUB_TIMEOUT=5
GRUB_DISTRIBUTOR="$(sed 's, release .*$,,g' /etc/system-release)"
GRUB_DEFAULT=saved
GRUB_DISABLE_SUBMENU=true
GRUB_TERMINAL_OUTPUT="console"
GRUB_CMDLINE_LINUX="rd.lvm.lv=fedora/root rd.lvm.lv=fedora/swap rhgb quiet"
GRUB_DISABLE_RECOVERY="true"
Can you perform these steps? Edit the line Grub-cmdline-linux-default = “quiet splash drm.debug=0x1e log_buf_len=4M” sudo update-gurb Reboot the machine and try to reproduce the error and attach the logs.

Have you done as said in comment 8? Also, I recommend to verify the issue with latest drmtip. (https://cgit.freedesktop.org/drm-tip) I did as you stated in comment 8 the output of grub2-mkconfig /etc/default/grub: line 7: splash: command not found /etc/default/grub: line 7: drm.debug=0x1e: command not found Also I'm not sure how to update to the latest build of drm-tip Can you try to verify with latest drmtip and see if the issue still persists? If drmtip is not possible for you, can you try with stable kernel? No response from more than a month. Closing this bug as WORKSFORME. |
