Slackware64 13.37 - external monitor madness
HP Probook 4530s, Core i5 2430M, 8GB ram, Intel HD3000 + ATI HD6490M (switchable graphics)
Slackware 13.37 64bit update to "current" with kernel 3.2.13 (huge),same problems with Slackware 13.37 64bit with 18.104.22.168/3.2.4/3.2.7 kernels
ATI proprietary Catalyst 12.1 / Driver ver. 8.93 (tried all versions from Catalyst 11.8 same thing)
Can't get 2 bloody monitors to run with this setup!!!
KDE System Settings -> Display and Monitor -> Multiple Monitors says "This module is only for configuring system with a single desktop spread across multiple monitors. bla bla"
AMDCCCLE - does NOT have any monitor/display settings.
Setting resolutions and position from System Settings -> Display and Monitor -> Size & Orientation resets both monitors to 1024x768 OR resets external to 1024x768 and keeps internal OK.
Tried ALL xorg.conf setups I could find, no luck, setting Xinerama On in xorg.conf screws System Settings -> Display and Monitor -> Size & Orientation which displays an error message.
can be found here:
xdpyinfo -ext XINERAMA
How AMD CCCLE looks can be seen here:
P.S. I have the same setup on a HP Probook 4510s with Slackware 13.37 32bit, custom compiled kernel and Catalyst 11.8 and works like a charm.
P.P.S. I posted this on another forum and had no luck with it so if you found it there please bear with me .
In order to find the culprit, could you try setting the monitors with the OSS driver? If a bug in the proprietary driver turns out to be the source of problem, then little could be done to help.
Just saw the "switchable graphics"... Looks like a tough one.
