A few pixels are missing at the left and right of screen
I have just installed Debian 8.0 (Jessie), amd64 port. I have a Samsung
E2420 monitor. The video board uses the AMD (ATI cedar) Radeon HD 5450
chip set. I had to install firmware-linux-nonfree to get the full 1920
x 1280 resolution.
In Jessie, a few pixels at the left and right of the screen are off the
edge of the monitor. The same thing happened in up-to-date Wheezy but
all the missing pixels are on the right side of the screen. If I adjust
the monitor to move the screen to the right, a black edge of the display
appears at the left side of the monitor, but the pixels are still
missing. My guess is that the monitor is displaying every pixel it
received. Perhaps the video driver or the software is chopping off the
display. How do I fix this?
