I have been running Slackware 8.1 and have installed NVIDIA_GLX-1.0-3123.tar.gz -and- NVIDIA_kernel-1.0-3123.tar.gz.
Everything was fine after I installed the nvidia drivers. Then about a month after I installed the nvidia drivers I started having problems. After I logout of a window manager and return to a terminal I get Vertical white lines like my screen is distorted. I double check my XF86config file and made sure to have
Driver set to "nvidia" - and to remove all entries
Load "GLcore" and Iv added Load "glx". Iv looked at all the logs there does not seem to be any problems I recently reinstalled slackware 8.1 and I still get the same problem. If anyone has any ideas it would be a big help.
