Hi all,

I am running a Fedora 23 workstation on a Toshiba Satellite 64-bit, processor Intel Core i7-3610QM CPU @ 2.30GHz × 8. The video card is: Advanced Micro Devices, Inc. [AMD/ATI] Thames [Radeon HD 7500M/7600M Series].

Since kernel-4.6.4 I started to have problems with my display resolution. I cannot adjust it and I cannot detect a second screen. In particular, it seems that the drivers are not found at all:

lshw -c video

   *-display UNCLAIMED

although package xorg-x11-drv-ati is installed.

Does anybody know what the problem could be here? Did maybe Fedora stop supporting this video card? Thank you for your help.

Did you install a AMD driver if so how how you installed?

AMD Radeon driver should be already installed (default). From yum: Package xorg-x11-drv-ati-7.6.1-3.20160215gitd41fccc.fc24.x86_64 is already installed, skipping.

That only means that the Xorg server package is installed not the kernel module, which is what you really need to make it work, review what lsmod tell you and look for radeon or AMD in the output, not sure of the name of the kernel module for your card. To do so open a terminal and type lsmod and enter.

Thank you for your answer. lsmod returns the output:

lsmod | grep radeon

Well now we know for sure that the AMD Radeon card kernel module is installed and running, what you experience maybe a bug or something because Fedora has not stop support your card. Are you using Gnome or other desktop?
