I'm adding my info here, because related to nvidia-270.41-06. All was working fine with kernel 18.104.22.168, nvidia-current-260.19.44, flash-10.2, Nvidia 8600M GS card
Later, after upgrading to nvidia-270.41-06, had noticed a regression of flash related issues, trying to upgrade to flash.10.3 didn't improve, so I went back using flash-10.2. But flash issue were still very annoying, therefore I decided to downgrade to nvidia-260.19.44.
Following JohnW suggestions http://www.pclinuxos.com/forum/index.php/topic,90668.msg760426.html#msg760426,
I'm finally back to a nearly full working behavior (still some minor flash issues).
What I want to highlight here is that the downgrade process/dkms-installation worked flawlessly for me. Looking at issues of other users, particularly at CJ
's issue, I would suggest to not look too much at nvidia driver version, but instead to look at dkms building process:
Preparing kernel 22.214.171.124-pclos1.pae.bfs for module build:
(This is not compiling a kernel, just preparing kernel symbols)
Storing current .config to be restored when complete
Running Generic preparation routine
make oldconfig....(bad exit status: 2)
cleaning build area....
make KERNELRELEASE=126.96.36.199-pclos1.pae.bfs SYSSRC=/lib/modules/188.8.131.52-pclos1.pae.bfs/build module....(bad exit status: 2)
Error! Bad return status for module build on kernel: 184.108.40.206-pclos1.pae.bfs (i586)
Consult the make.log in the build directory
/var/lib/dkms/nvidia-current/270.41.06-1pclos2011/build/ for more information.
For some reason, the build process is failing at time of "make oldconfig" and this can be a symptom of a bad kernel-devel tree, but can't exclude others causes.
A successive report from CJ
, while trying to downgrade to nvidia-260.19.44 show a similar failure: http://www.pclinuxos.com/forum/index.php/topic,90668.msg760489.html#msg760489
and I'm more convinced that something is broken, but it's not the nvidia driver.
My 2 cents
