Yes I do understand why you might call that corruption. Actually you didn't need to enable DRM debugging. It looks like there are a few errors coming from the Intel kernel graphics driver 'i915'. Those might be separate to the FIFO underrun errors, which other people also report in bug 1550779.
The problems reported in your kernel log seem to relate to atomic mode setting, which is what the 'modeset' Xorg driver uses. Wayland sessions don't use that interface to Intel graphics so it's likely that logging into 'Ubuntu on Wayland' will avoid some (or all) of the problem. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890436 Title: VGA signal is ghosted and stretched (Intel® HD Graphics 2500) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890436/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
