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

Well this is a PC with onboard intel graphics. A memory issue would mean RAM problem which is not the case here. I can see a visual corruption. If you can't see it then there is nothing more to say here. You are welcomed to see the dmesg and figure out what happens. There is no hardware damage on my PC. This occurs with a specific BIOS setting as I described above and it affects only ubuntu. Windows 10 2004 work fine on my "damaged" PC. If you wish to get a screenshot from windows working fine, I can upload it here. I might test wayland at the evening but linux kernel detects the problem and shouts about underrun error in FIFO A as the first attached image with dmesg shows. So if you have anything usefull to write that is related to this bug report, please do so. If you just continue to say that my hardware is damaged you are free to close this bug right away. I will try another distro and open another bug there... -- 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

It might be that there's some minor damage to the VGA port on the machine. It might be so minor you can't even see it :( -- 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
