Display shifted after logout

Post by croiwen » 2019/06/07 14:49:06

Hi everybody,

I have a really weird problem at a Centos 7-desktop. It features a Geforce 9500 on the nouveau driver with 2 Samsung monitors.
After logging out and reactivating the monitor, the left (primary) screen is shifted to the left - up to an amount, that cannot completely be fixed by the monitor's settings (horizontal position/ auto adjust). So it leaves a two inch black column on the the right side of the left screen.
When trying to adjust the screen using xrandr like this
xrandr --output DVI-I-1 --auto --mode 1920x1200 --pos 0x0 --rotate normal --primary
xrandr --output DVI-I-2 --auto --mode 1920x1200 --pos 1920x0 --rotate normal

it actually ignores the black pixels and continues on the right screen. The only solution I could find was to reboot the computer. Any ideas how to fix this without rebooting?

Thanks in advance!

I'm not confident about that. As an alternative, have you considered using nvidia-detect from elrepo to see if there's a driver for that card? If so, it'll tell you which one to install. In my case is was kmod-nvidia which pretty much keeps itself updated without intervention.

- just an idea -
Remember - importing/building packages will likely "byte you in the butt" come update time, long after you'd forgotten you did that! Use repos whenever possible.
