The 1.17.2 CentOS 7 Xorg server has a built-in driver "modeset(0)" that
works for most of the big 3 gfxchips. Some distros have made the internal
driver the preferred driver for certain gfxchips. To try it can be as simple
as removing all Xorg driver packages applicable specifically to your gfxchip
and restart the server. If you have xorg.conf* configured to use a specific
driver, or use an xrandr startup script to configure Xorg, then it would
need to be removed or adjusted accordingly.
My problem is that I'm a "install it and forget it" person so I don't
have much experience poking around in xorg.conf.
AMD helpfully provides an uninstall script, which seems to have worked
but may have left some items installed (uninstall log was decidedly
unhelpful). It left me without an xorg.conf at all so the driver
picked a generic config. Problem is that I have displays on both DVI
connectors and the HDMI connector. The default doesn't see that. I
tried using aticonfig to generate an initial config but that leads to
no display and a warning about "kernel module (fglrx.ko) may be
missing or incompatible ".
Really not sure where to go from here which is why, initially, I'd
installed all the AMD/ATI stuff (including their GUI control panel).
But I can confirm that the AMD drivers aren't very good. The problem
with konsole exists when I run Opera, too, in addition to Chrome. And
I'm really tired of Firefox. :-)
