I have a monitor that supports 2560x1080. While I have a Radeon 5450 graphic card, running Debian Jessie, I only can get 1920x1080. I installed firmware-linux-nonfree to get it running. Why isn't my complete resolution listed?

Installing fglrx-driver using apt-get

I have to mention that sudo apt-get install fglrx-driver gives me the following error:

sudo apt-get install fglrx-driver

According to debian-wiki you need to install linux-headers and fglrx-modules-dkms

First add the following line to your sources.list:

deb http://httpredir.debian.org/debian/ jessie main contrib non-free

Then type the following command:

aptitude update
aptitude -r install linux-headers-$(uname -r|sed 's,[^-]*-[^-]*-,,') fglrx-driver

Create the confugration file 20-fglrx.conf

mkdir /etc/X11/xorg.conf.d
echo -e 'Section "Device"\n\tIdentifier "My GPU"\n\tDriver "fglrx"\nEndSection' > /etc/X11/xorg.conf.d/20-fglrx.conf

Reboot and verify your résolutions.

  • Installing fglrx-modules-dkms gives me the same errors from insalling proprietary driver from AMD website May 28, 2016 at 1:40
