No GUI after SLES11 SP3 x86_64 install when monitor on KVM
My hardware is HP DL380p G8 server, HP LA2405wg monitor, IP Server Console Switch (KVM) AF616A. SLES10 SP4 x86 and SLES11 SP2 x86_64 work fine with same hardware. Once install of SLES11 SP3 x86_64 completes, the monitor displays "Input out of range. Change settings to 1920x1200". HP Support says this is OS problem and won't help. Note: There is no problem if this monitor is direct connected to the server. I use autoyast for install, but the same problem occurs if manual install is performed.
Last few lines of Xorg.0.log are:
(II) config/hal: Adding input device Avocent HP 336047-B21
(EE)config/hal: NewInputDeviceRequest failed (8)
embedded graphics is Matrox G200 eH
driver is : XFree86 v4 Server Module: mga
Workarounds I've found are:
1) overwrite xorg.conf with xorg.conf.install, reset X, then use sax2 to select higher resolution (highest modeline in xorg.conf.install is 800x600 - there are no modelines in xorg.conf)
2) put this monitor's vert and horiz sync info into <x11> tag of autoyast file - but this is not practical as a different autoyast would be needed for every monitor we might install on.
I'm looking for a solution that can be included in autoinst.xml that will work for most monitors. Any ideas?
