When launching KDM login manager, the screen goes crazy and the system
Steps to Reproduce:
1. Edit settings in /etc/inittab and set default runlevel to 3.
2. Reboot and login.
3. Type "kdm" at the prompt.
Actual Results: X begins to start, but then the screen gets distorted
(like vertical colored lines) and the system locks up.
Expected Results: The KDE login manager should have appeared.
My system has an S3 Savage4 card w/32 MB memory. I have never had this
problem in RedHat 7. I login as usual, but upon typing 'kdm', the X starts
to load and the system hangs. Typing 'gdm' works okay. I don't know if
this is a KDE bug or what. I know one thing, XF86 4.0.2 doesn't like my
card very well (I can't have a high resolution and I can only get 16 bit
colors. In XF86 3.3.6, I could get as high a resolution as wanted with up
to 32 bit colors. Perhaps you could change this and make using 4.0.2
optional during the setup??? I would really appreciate that!). I can load
KDE with no problems from GDM, I just can't launch KDM. I have had no
other X or KDE related prolems. Well, thank you guys again!
By the way, my system is a PIII 500MHz with 128 MB of RAM.
Can you reproduce this behavior with Wolverine?
Yes, I can indeed reproduce this with Wolverine. I tried setting KDE as my
default desktop during the setup, and when I rebooted the screen blanked and
the system froze while loading KDM. GDM works perfectly.
This could be a duplicate of bug #29627... Which graphics card are you using?
I'm not exactly sure, but I know it uses an S3 Savage4 chipset. I would like to add that the XFree86 4.0.2 Savage drivers don't work well. Could you make using XF86 4.0.2 an option during the install? 3.3.6 had better support.
Assigning to XFree86. Please try the current XFree86 packages from rawhide and
let us know if this problem persists.
Please try XFree86-4.0.2-11.4.0 and Mesa-3.4-11 from:
ftp://people.redhat.com/mharris as well as Xconfigurator from Rawhide
Does this fix the problem for you?
Also, using XFree86 3 or 4 _is_ an option. To use one or the other use:
