Hello, thank you for your early reply! I am afraid that you haven't got the big picture here. On my side, there is no doubt that I am getting a visual corruption. Just take a look at the attached images.
The video signal is good since the monitor works normal when I enable CSM setting in BIOS. As you have suggested, I used a different VGA cable having double thickness than the initial one and I am still getting the same behaviour. If it was a signalling issue the kernel would probably not print any warning messages. Since I have another VGA monitor on my desk, I went a step ahead and connected this VGA monitor instead since I hadn't tested this case with that monitor. As expected, I got exactly the same behaviour. That is smooth display on VGA monitor when CSM is enabled and corruption when CSM is disabled. As a proof of it, I am uploading images from the third monitor. Take a closer look at the cursor as it has blank lines after each horizontal line. As you can see, the same applies to fonts when switching to console view. I am also uploading the X log with that monitor. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1890436 Title: VGA image is ghosted and stretched (LG L1953S) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890436/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
