boot screen off center, 1/3 right appears on the left

With OpenSuse 12.3, many of the boot-ups start with the screen off-center. (1/3 right appears on the left)
The screen stays shifted after desktop opens.

With same computer when booting into LinuxMint this never occurs.

Dell XPS 8500
i7 3770
AMD radeon HD7570 (Turks)

It could be a bad video configuration but I wonder if a kernel change (like going to 3.8) might help in any way? Have a look here: openSUSE and Installing New Linux Kernel Versions - Blogs - openSUSE Forums

Thank You,

Which graphics driver is installed/used?

radeon or fglrx?

(not certain if this answers what graphics driver) (used Kinfocenter, selecting: OpenGL)

Vendor _______ X.Org
Renderer ____ Gallium 0.4 AMD TURKS
OpenGL/ES ____3.0 Mesa 9.0.2
kernel module___radeon

@maclion

with the radeon driver installed, do the following checks,

  1. if the directory /usr/share/ati/ exists, run any script with uninstall in it,
    – if necessary run it with parameter --force

  2. verify there is not a file named /etc/X11/xorg.conf,
    —if there is rename it to something else

  3. in -yast, --Sytem, —/etc/sysconfig Editor,
    – search for NO_KMS_IN_INITRD and verify it is set to no, if not change it to no
    – then press ok to accept

  4. in -yast, --Sytem, —Boot Loader, ---- Boot Loader Options,
    ----- Optional Kernel Command Line Parameter
    – if there is the parameter nomodeset there, delete it
    –(or any other parameter with modeset in it)
    – then press ok to accept

  5. if any of the following files exist,
    /etc/X11/xorg.conf.d/50-device.conf
    /etc/X11/xorg.conf.d/50-monitor.conf
    /etc/X11/xorg.conf.d/50-monitor.conf
    /etc/X11/xorg.conf.d/50-screen.conf
    — make sure every line in each file is commented out, starts with a #
    (its assumed a standard monitor is installed)

with the above a clean reboot to the radeon driver should be possible

if the above does not correct the graphics, post here the output of cmd,

lsmod | grep radeon

and

rpm -qa | grep kernel

hth

Found a nomodeset parameter in Boot Loader Options and deleted it

First reboot, screen **normal. **

Your help is appreciated

Ran terminal commands as a point of reference.:

gary@linux-2d5s:~> lsmod | grep radeon
radeon 983503 3
ttm 91793 1 radeon
drm_kms_helper 53448 1 radeon
drm 297794 5 radeon,ttm,drm_kms_helper
i2c_algo_bit 13413 1 radeon
gary@linux-2d5s:~> rpm -qa | grep kernel
kernel-desktop-3.7.10-1.1.1.x86_64
kernel-firmware-20130114git-1.2.1.noarch
kernel-desktop-3.8.6-2.1.x86_64

Normally, the nomodeset command should only be used if you are trying to install the proprietary video driver and don’t want the default KMS driver to be used. If you are not doing that, then the nomodeset command should not be used. Do consider that it does exist in the recovery kernel loads on all systems by default. You can examine these settings better with my grub2 bash script you can find here: GNU Grub2 Command Listing Helper with --help & Input - Blogs - openSUSE Forums

Just to show you’re not alone with this Radeon trouble, see
https://bugzilla.novell.com/show_bug.cgi?id=803026
I see I’ve forgotten to respond to the last query on that report so I’ll
have to get snapping. Slapped wrist for me.
