KDE 4.6.0 and nvidia drivers

Sat Apr 30 16:39:48 BST 2011

You don't say which kde version you are using. As far as web,mail and the 
editors go I haven't seen any problems at all with nouveau and 64bit kde 4.6.0. 
I did have one or two instances as you describe on 32bit. I installed the nvidia 
driver very soon after loading it though. For all I know that might have been 
the cause. Some of the lock up's seem to be down to something sleeping for far 
too long and maybe building up excesses in the queue can cause further problems. 
I now install no acpi and haven't noticed that sort of delay on either 32 or 
64bit. All I had on 32 then was missed mouse clicks or they seemed that way to 
me. Could be changes in kde.

On 64bit which I was reluctant to install due to past problems with finding 
64bit apps I installed 32bit Opera without any problem. My package manager 
complained but just downloaded a lot of 32bit libs. There does seem to be a very 
slight performance problem. New tabs and tab closings sometimes have a 
noticeable delay. I am very sensitive to spotting that sort of thing though.

As to nouveau I have the window fading which I find useful as I can read what's 
underneath but sizing a window with the mouse is a joke. It will track so far, 
then fall well behind and then stop. It catches up when the mouse button is 
released. Sort of OK but messy.

I'm just about to try and install the nvidia driver on 64bit.

On problems in this direction maybe with either driver I did see something on 
the web somewhere relating to "noflip" causing problems one way or the other. No 
interest at the time so no further info.

Opensuse 11.4 kde 4.6.0 - 6.

This is my story:
I'm using Fedora (now 14) on my HP HDX-18 with an nvidia GPU.
I don't want to use any closed driver since I need a very little 3D 
performances (I'm using only the simply KDE effects: "show all 
windows"...that's it!):so, I'm using the noveau driver.

Well, my machine freezes once a day: I can still ssh in it and reboot 
nicely but the X system doesn't respond! (I can't copy/paste here the 
Xorg.log but I can see noveau errors).
And yes, the freeze occours even if I don't enable the desktop effects.

>From a couple of days I'm using gnome (no desktop effects) and my work 
is running smootly.

This is *NOT* the solution, but, rigth now, it gives me some oxygen in 
order to try to investigate on the problem. I really don't know if the 
problem is noveau || kde || kwin || hw problem || bad luck, but this is 
my story!
