Thanks for the bug report. The attached Xorg logs appear to be from before the bug as they show a resolution of 1600x900. But I can also see that your current resolution is 800x600 in Xrandr.txt. It seems Xorg now can't even tell what kind of monitor connection it is.
Please try booting an older kernel by accessing the grub menu (press Esc at startup). Do you find older kernel versions avoid the problem? Please also try unplugging and reconnecting the monitor. ** Package changed: xorg (Ubuntu) => linux-hwe-5.11 (Ubuntu) ** Changed in: linux-hwe-5.11 (Ubuntu) Status: New => Incomplete ** Summary changed: - My resolution has changed to 800x600 , it was in higher than 1000 I dont know the exact no + [i915] My resolution has changed to 800x600, it was 1600x900 before -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1943154 Title: [i915] My resolution has changed to 800x600, it was 1600x900 before To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.11/+bug/1943154/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
