How to downgrade from 11.2 to 11.1

camper365 · #1 (**permalink**) 07-Nov-2009, 11:26

I am new to openSUSE but I have been using Ubuntu for a while. I tested Karmic for 6 months and then got really mad at Cononical for various reasons and decided to switch to openSUSE.
I downloaded the 11.2 RC2 on CD and found that it freezes a lot of a Thinkpad T43, so I would like to downgrade without reinstalling. Is this possible? I know that in Ubuntu you could edit the /etc/apt/sources.list file but is there a file like that in openSUSE?

Re-Install - The partitioning of 11.2 is not compatible with 11.1

or work on solving your problem in 11.2
I'm sure we can help

You could try and solve the freeze problem. Is this KDE4 you are running on 11.2 RC2 ? Does this freeze happen only when PC is plugged in? Only on battery ? Both ? Some users reported the screen save and the power save have caused problems. If this only occurs when the laptop is plugged in, try changing the characteristics of the power save so as not shut the PC down when Plugged in.

There may be other things you can try as well.

Is there any indication in /var/log/messages indicating why the PC froze? You will need to use root permissions to open that file.

The freeze typically occurs when I switch from any tty back to kdm. I think it has something to do with my configuration, because the freeze doesn't occur when it is prompting for login, but does when I am logged in. I don't think the "freeze" is really a freeze because the screen turns black, but the mouse is still visible and works. However, the trackpoint does not work, but the touchpad does. I am able to use the magic SysRq key, but am unable to switch to a tty. Ctrl+Alt+Del seems to do something (the hdd light flashes) but does not completely reboot. It doesn't matter whether the computer is plugged in or not, the freeze still occurs. I have found that occasionally the freeze doesn't occur, but it is relatively rare. But when the freeze doesn't occur one time, it doesn't occur no matter how many times I try.

What graphics in in that ThinkPad?

Check the hidden .xsession-errors file for clues.
Sometimes it's handy to delete the current one first.

Update: When I use Alt+SysRq+K during the "freeze" I can successfully get back to the login screen, but going to a tty is no longer a logical option. I am able to go to one, and do whatever I need to do, but the display is pixilatted on the top and a still image of whatever was on the X server before on the bottom (nonfunctional though). There is a response, but an illegible one when I type characters.

it is an ATI Radeon X300.

I have checked .xsession-errors, and found this:

Code:

X Error: XSyncBadAlarm 154
  Extension:    144 (Uknown extension)
  Minor opcode: 11 (Unknown request)
  Resource id:  0x0

I'm not sure what it is, but it came right before:

Code:

kdeinit4: preparing to launch /usr/lib/libkdeinit4_kcminit_startup.so

so I'm thinking this XSyncBadAlarm is the problem. I just have no clue what it means

Have you installed the ATI video driver for X300?

To find out what graphic driver is being used in openSUSE-11.2 you can type:

Code:

 /usr/sbin/hwinfo --gfxcard | grep river

the output of that command was:
