Hi, I run Arch linux with KDE 4.2 on a machine with a Geforce 6200 LE card. But recently I have been experiencing some weird things. At the begining I was running KDE 4.2.0 with a nvidia-180.22 driver and the X process consumes lots of memory graduately, even to 200+ MB some times. Then I updated to KDE4.2.1 and the problem disappeared. But today, after I update the video driver to nvidia-180.29 it is here again. I have no idea which component cause it. KDE, nvidia dirver or xorg? Another weird thing is with the nvidia driver. Before updating to 188.29, glxgear had about 1060 FPS. After update and I restarted the KDE. Then glxgear told me the nvidia api dismatch, that is, the kernel module is still 180.22 but other parts of the driver is 180.29, and it has 1300+ FPS, then I remove the old module and modprobe the new one so it runs 180.29 now, but it is 1060FPS again. There's no improvement over 180.22! What's the problem?
