Re: Slow desktop

Maybe I am wrong but it seems like your graphic card isn't set properly anymore in your KDE environment.

Re: Slow desktop

It's a laptop, it probably uses onboard graphics.

Re: Slow desktop

my graphic card is a 128mb nvidea, ( 32 dedicated ) NVIDIA GeForce Go 7200.

Re: Slow desktop

Can you check if "nvidia-glx" is installed? Use Adept to look for it.

A laptop with graphics cards?! What's next, water cooling for laptops?

Re: Slow desktop

They intentionally omitted "integrated".

Re: Slow desktop

I looked for "nvidia-glx" in adept it was not installed so i installed it, if it made a difference its very slight, windows now close and open a tiny bit better, but still far lacking what it used to do and what gnome is doing.

Re: Slow desktop

You now need to edit /etc/X11/xorg.conf as root, changing the "driver" line in the "Device" section, so that it reads 'driver "nvidia"'. It should read "vesa" or "nv" now.

Re: Slow desktop

Ok i edit'd the line and restarted and no GUI would appear, just ubuntu logo and a flashing " _" thats it!, i went into recovery mode and undid the changes to xorg.conf
So whats going wrong?
I have a copy of xorg.conf here and highlighed the bit i tried to change

Re: Slow desktop

Leave "nvidia", go to the regular command prompt in text mode, login and try "startx". See what error is output.

Re: Slow desktop

Or just try to start X with it as "nvidia" and post the output of "grep WW /var/log/Xorg.0.log && grep EE /var/log/Xorg.0.log".
Your choice.

Re: Slow desktop

Ok i changed the line back to Driver "nvidia" the did a reboot, and same as before ubuntu logo then nothing i waited still nothing, then did a boot up in recovery mode and got the promt and typed
> startx
The screen gave a quick flash and back to the black promt with the following error, which i will summarize becaue i dont know how to copy and past it into nano

X window system Version 7.2.0
Release date 04 april 2007
....
(EE) Failed to load module "nvidia" (module does not exist,0)
(EE) No drivers availble

Fatal server error
No screens found

So i gues im missing something

Re: Slow desktop

Hi again, i was in gnome and just did a synaptic search for nvidia and took the nvidia glx option ( which i was sure i had already done in adept, but i did also chosse someother options last night that could have removed the glx file and i may not have been aler to it )

Cool, you can now close the thread with SOLVED. =)
Nice to hear you got your KDE running fine.
