Since there was no option to perform this task, I modified some settings. In detail, I disabled CSM in BIOS and that's when hell broke loose! To get an idea about the hardware, the Lenovo machine isn't running the latest BIOS as its updater is broken and won't update it within win or its ISO image. It uses the previous version released by its manufacturer. The machine has an XGA VGA monitor and a WQHD DP monitor. When CSM is enabled the DP monitor is lit first and then the VGA one prior OS loading. When CSM is disabled it goes the other way around. The VGA monitor is lit and the DP one opens up during OS load. With CSM disabled the VGA monitor is the primary one and it is corrupted as you can see on the pictures I have attached. Interestingly printing screens within Ubuntu does not capture the corruption problem I am getting as you can see on the pictures I have also attached. Neither X log contains anything useful. The issue is repeatable on every boot. As I have seen on other bug reports, I have enabled DRM debug, captured the dmesg using a huge buffer to get it and have uploaded it as well. I hope that it will help you track this issue down and fix it soon. Since I will be away some days for vacation, I will have physical access to it till this Friday and will get back to work at the 24th of August. In the mean time, I hope that someone will pinpoint the root cause of it and prepare a patch. Since this machine is running w10 2004, it should be noted that in win I do not get any corruption at all either in CSM mode or UEFI mode.
