[elrepo] ATI Radeon R7 240

Mon Feb 29 08:58:31 EST 2016

Hi,
I reinstalled centos and chose the 'Gnome Desktop' packages, after that I was able to startx normally. Installed the kmod package and everything looks good (even though the 'no UMS support' appears during boot). 
Thank you very much for your help !

  I went ahead and: yum groups install "GNOME Desktop" 
 I assume that you already have the X server and fonts installed because AFAIK they are not brought in by the Gnome desktop group.

 yum install --enablerepo=elrepo-testing kmod-fglrx fglrx-x11-drv-32bit 

 I've never needed fglrx-x11-drv-32bit

  Than I got  *ERROR* No UMS support in radeon module! 
  So after checking this: https://www.centos.org/forums/viewtopic.php?f=49&t=52131 
 That post is kind of outdated unfortunately.

 I added  Section "Files"         ModulePath "/usr/lib64/xorg/modules/extensions/fglrx"         ModulePath "/usr/lib64/xorg/modules" EndSection 
  to xorg.conf 
 One year ago this was needed but the current packages ( since last summer actually ) add these options at install time via /etc/X11/xorg.conf.d/20-fglrx.conf and also move a stock , conflicting library out of way.

  and removed all the 'nomodset' references added to the grub.conf 

 At install time, the fgrlx-x11-drv package disables the stock radeon driver by adding "radeon.modeset=0 rd.driver.blacklist=radeon" to the kernel command line

  Now this fixed the UMS error however, after I do startx nothing happens.

 ... and the driver seems to work OK

 Not sure what I'm missing now. 
 If you can, please restart from scratch.
 a) restore the system to a pristine condition ( including here the removal of xorg.conf and any modifications you did to grub.conf ).
 b) do a yum install --enablerepo=elrepo-testing kmod-fglrx 
 c) reboot
 Normally step d should be "enjoy", If the system boots but you have a black screen, please switch to a text console ( ctrl-alt-F2 ), run ps -axfw > /tmp/ps.txt, pastebin somewhere the content of /tmp/ps.txt  and then contact me via freenode.net / #elrepo
 If the 32bit drivers are needed in order to get rid of the "no UMS support" error, please let me know so that we can add it as a known issue in the wiki page
