3d acceleration issue in KDE
- Anmelden oder Registrieren um Kommentare zu schreiben
I have a NVIDIA 9500GT card which provides me with 3D acceleration. Games or applications which require it (e.g. Extreme Tux Racer, Stellarium) work absolutely fine in GNOME. In KDE, I can enable desktop effects and some games which require 3D acceleration (e.g. Open Arena) work perfectly, BUT the aforementioned games/applications (Stellarium, Extreme Tux Racer) that work fine in GNOME are choppy (the screen keeps on 'blinking') in KDE.
Where does KDE interfere here? How can I fix this issue? Thanks!
By the way, I hadn't installed libgl1-mesa-dri-experimental since everything worked fine without it. Installing it didn't change anything.
It might be KDE's compositioning manager. I've had issues with it before, as well as plenty of other issues, so I just stopped using KDE. Does it happen when you turn off its desktop effects and try again?
I'm honestly not too sure how many people here use KDE, so I'm trying my best.
Hello miga,
You are right! I was just going to add that I had found the culprit. Disabling the desktop effects fixes the issue. I will try to see if a specific desktop effect is to blame, or if it's the whole setting that creates problems for these applications.
By the way, you have a very good question :). How many people here use KDE? I have been using it for the past days, as a gesture of defiance towards the to me bad direction that the GNOME project is taking, and I am quite sold on it now. Funny because I found KDE quite ugly and unstable when I first tested it 2-3 years ago, but it has gone a long way and I must say I really like it now!
EDIT: problem solved by checking the 'Disable desktop effects for full screen windows' box in the Desktop Effects configuration panel.
I as well don't like the direction GNOME's taking.
I really like what Trisquel's doing, however, in making GNOME 3's fallback shell probably the best version of GNOME 3. I still don't use it however, since I don't use Trisquel (I use Parabola instead, another free distribution based off of Arch). I use my own scripted desktop environment based off of Compiz, XFCE4's panel, Docky and GTK2/Qt applications. Honestly, it's better than any desktop environment I've ever used, probably because I built it to suit my needs.
I've tried out KDE somewhat recently, and while it does look quite pretty, I just could never get used to it. However, I gladly used it for a short time when GNOME 3 came out, as I found it absolutely terrible and unusable.
