Recently did an upgrade from Mandriva 2010.2 to 2011.0, which includes KDE 4.6.5. Everything on the desktop is painfully slow, like watching a video in slo-mo. Hi-lighting from one menu icon to its neighbor takes 2-3 seconds.

I have an nvidia 6100 installed, and its driver is 280.13. Not up to the minute, but certainly adequate.

I renamed the .kde4 directory out of the way to make another application function. Fixed that problem, but the slowness is still there.

Desktop effects are disabled. When I tried enabling them, I lost the mouse cursor altogether.

It was fine on the previous version of Mandriva, but not sure which version of KDE that was.

Where to look, what to try?

Thanks,

what's the result of lsmod|grep nouv ?

Null

[kd1yv6@localhost ~]$ sudo lsmod|grep nouv
[kd1yv6@localhost ~]$

Is that good or bad?

it's good in that the problem isn't that you have the nouveau drive installed by mistake (I've seen that happen).

run sudo lsmod|grep nvidia to make sure the Nvidia module is loaded

when you upgraded did the Nvidia driver package get upgraded also? If you self compile, did you recompile the driver?

Code: Select all

lspci -nnk | grep -i vga -A2

will give you hardware and currently used driver. If I were you I'd google for the best driver for your video card and install that.

sudo lsmod | grep nvidia
nvidia 10384336 30
i2c_core 25410 2 nvidia,i2c_i801

is what it returned before I made the change which relates to the following post. After that change, it returns null.

03:00.0 VGA compatible controller [0300]: nVidia Corporation G96 [GeForce 9400 GT] [10de:0641] (rev a1)

Kernel driver in use: nvidia
Kernel modules: nouveau, nvidiafb, nvidia, nvidia-current

This led me to the correct solution. drakconf Display did not list this nVidia model, nor anything close to it. The system had defaulted to the nVidia 6100 series, but that seems to have been the cause of the pain.

I scrolled past the nVidia list, and I think I chose Xorg. Under there, nv was a listed option. I selected it, and installed, and all seems to be right with the world, at least for now.

Thanks for the tips.

Glad it worked. Could you please mark this topic as solved - thanks
