This is a new feature to compensate for the overscan imposed by lots of TVs. To disable it: xrandr --output HDMI-0 --set underscan off This bug is a duplicate of: https://bugzilla.kernel.org/show_bug.cgi?id=20142 |
Created attachment 34512 [details] The dmesg with 2.6.36 kernel Hello, I've got a strange bug since I've installed the new 2.6.36 kernel. KMS configure my screen with the right resolution, but the display doesn't seem to fit the actual screen size. When I look at the properties into the screen OSD, it shows that it works at 1920x1080 (1080P). As a result of this, the resolution is correct but the display is smaller than this, so I've got black lines and my display is blurred. I could reproduce the bug on two different screens, two different radeon GPUs and with two different configurations of the kernel. As I use an HDMI connection, I tried with the VGA one but it doesn't permit me to display such a large resolution.
