Description Joe Morris 2001-02-23 18:14:07 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.0; Windows 98; DigExt)

When launching KDM login manager, the screen goes crazy and the system 
locks up.

Reproducible: Always
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?
Comment 3 Joe Morris 2001-03-03 09:08:45 EST
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?
Comment 5 Joe Morris 2001-03-06 08:33:51 EST
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.
Comment 6 Bernhard Rosenkraenzer 2001-03-06 08:38:22 EST
Assigning to XFree86. Please try the current XFree86 packages from rawhide and 
let us know if this problem persists.

Comment 7 Mike A. Harris 2001-03-13 00:50:01 EST
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?
Comment 8 Mike A. Harris 2001-03-13 00:53:28 EST
Also, using XFree86 3 or 4 _is_ an option.  To use one or the other use:
Xconfigurator --preferxf3
Xconfigurator --preferxf4
