[Bug 1890436] Re: VGA image is ghosted and stretched (LG L1953S)
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 Bugs, which is subscribed to 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

This looks like a signalling problem. There doesn't seem to be any corruption in the image. Only the signal to the monitor doesn't correctly match the frequencies that the monitor requires. As a workaround please try selecting 'Ubuntu on Wayland' from the login screen. Please also try a different VGA cable if you can. ** Summary changed: - Screen corruption with multi monitor setup + VGA image is ghosted and stretched (LG L1953S) ** Package changed: xorg (Ubuntu) => xorg-server (Ubuntu) ** Also affects: linux (Ubuntu) Importance: Undecided Status: New -- 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 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 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
