After last upgrade I can't enable ATI driver. Before I needed to disable KMS due to system freeze issues.
I used xf86-video-ati-6.14.6-2 package all the time, because new one caused problems.
After last upgrade Xorg stopped to boot with xf86-video-ati-6.14 and I had to upgrade it. But xf86-video-ati-1:7.1.0-1
doesn't work with disabled KMS and now I stuck with VESA driver.

Does anybody has any idea how to resolve this ?

OK, I have found workaround.
Disable KMS in /etc/modprobe.d/radeon.conf, otherwise system will not boot
options radeon modeset=0
#!/bin/sh modprobe -r -v radeon drm modprobe -v drm debug=1 modprobe -v radeon modeset=1
Create systemd init script /usr/lib/systemd/system/rc-local.service:
Description=/etc/rc.local Compatibility ConditionPathExists=/etc/rc.local [Service] Type=forking ExecStart=/etc/rc.local start TimeoutSec=0 StandardOutput=tty RemainAfterExit=yes SysVStartPriority=99 [Install] WantedBy=multi-user.target
Now Radeon driver works with KMS, will see if I have system freeze
Thanks this worked for me. Spent ages looking for an answer to this.
Just one thing, don't forget to chmod +x the rc.local or it won't work.
I have same problem with my thinkpad x120e. Will try your workaround.
