I wonder if anyone has CentOS-6 working on an HP MicroServer? I'm having a problem with the graphics driver for the Radeon HD 4200 graphics card.
CentOS-5.6 is working fine on this machine; but at present I only have CentOS-6 running in text mode.
The graphics card as given by "/sbin/lspci -m" is ------------------------------- 01:05.0 "VGA compatible controller" "ATI Technologies Inc" "M880G [Mobility Radeon HD 4200]" "Hewlett-Packard Company" "Device 1609" -------------------------------
The Radeon related modules are ------------------------------- [tim@grover ~]$ lsmod | grep -i radeon radeon 798300 0 ttm 47134 1 radeon drm_kms_helper 32113 1 radeon drm 202185 3 radeon,ttm,drm_kms_helper i2c_algo_bit 5664 1 radeon i2c_core 31274 5 i2c_piix4,radeon,drm_kms_helper,drm,i2c_algo_bit -------------------------------
Under CentOS-5.6 the Radeon related modules are ------------------------------- [tim@grover ~]$ lsmod | grep -i radeon radeon 148193 0 drm 115561 1 radeon -------------------------------
Admittedly I have probably installed different packages in the two cases.
I'm wondering if I could try the old radeon module, and if so how?
Are there any documents that might help me determine the problem, and hopefully solve it?
I don't see any errors listed in /var/log/messages, or in dmesg.
Any suggestions or advice gratefully received.

It seems to me that the problem may arise from the lack of config-system-display in CentOS-6.
I see that under CentOS-5.6 the file /etc/X11/xorg.conf was created by config-system-display . The corresponding file under CentOS-6 is very short: -------------------------------- Section "Device" Identifier "Videocard0" Driver "vesa" EndSection -------------------------------- Is this file used at all in CentOS-6?
According to http://www.linuxtopia.org/online_books/rhel6/rhel_6_migration_guide/rhel_6_migration_chap- Migration_Guide-Package_Changes.html "The system-config-display tool has been replaced by XRandr configuration tools" Unfortunately I've no idea how to use XRandR, and the documentation for this is not much help.

I've managed to get the machine into graphics mode, after following the advice in http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html- single/Installation_Guide/index.html to add xdriver=vesa to the kernel line in grub.conf .
I'm not sure if vesa is a different driver, or is it a mode for the radeon driver? It does not seem to appear as a module under lsmod ; the same radeon modules as before are listed.
