Hi, this time it may not be the fault of nvidia (i am on nvidia too)... as I heard similar reports for ati and intel... and someone was blaming mesa... I suspect you are using oxygen... if you change to something else do you still have issues? Alin On Thu 16 Jun 2011 06:19:47 Michael Powell wrote:
Greetings all:
I had been stymied in upgrading my 11.4 system to 12.1 M1. The upgrade would proceed as normal, but the Nvidia drivers versions 270.xx.xx and 275.xx xx (all the proprietary xxxx.run file downloaded from Nvidia) would be required for use. The kernel module would not build for 260.19.44 under 12.1 M1.
The 260.19.44 driver is the last one for which desktop effects worked correctly for me. With the 270.xx.xx and 275.xx.xx I had to disable desktop effects due to various problems. Even then, there was still a problem with the titlebar blacking out in the middle when hovered over in some window decorations. So I wanted to figure out how to get the 260.19.44 driver to build the kernel module under 12.1 M1.
Turns out it was simple. Extract the NVIDIA-Linux-x86_64-260.19.44.run with the -x switch. Change into the NVIDIA-Linux-x86_64-260.19.44/kernel directory and open file nv-linux.h and change line 90 from #include
to #include . Logout from KDE, login to console as root, init 3, cd to wherever the above directory was extracted and run the nvidia-installer as you normally would. Driver installs, reboot, and now you can turn the KDE/KWin Desktop Effects on again and everything is running the way it did under my old 11.4. As far as any deeper stuff is concerned, such as the classic NVIDIA vs KWin devs back and forth I can't address (way out of my league). I believe this problem is triggered with the move to the 2.6.39-2-desktop kernel. Unclear as to very specific details, but I seem to recall some mention of kernel locks removal. All I can say is I am happily running the 260.19.44 driver under 12.1 M1 and Kwin Desktop Effects are once again running fine.
As to why others have not seen this I do not know. I do hope this may help anyone who may encounter what I did. This is not the correct approach for a long term fix, but it is maybe a good interim solution for now. My hardware is nothing special - it's only a Nvidia GTS 450. It would really be nice if NVIDIA would fix their drivers, which is what I was initially waiting for - but when 275.09.07 dropped and they had not I went looking for this work around.
