Gentoo Linux – Toshiba Satellite X200/X205 (part3)

The Frame Buffer/Nvidia/Xorg problem

To get the frame buffer support I compiled the relavent sections into the kernel and added "video=vesafb:mtrr:3,ywrap vga=865" to the kernel line in my grub.conf. The framebuffer works correctly and with these settings. It is then possible to load gdm and enter gnome without issue. The problem comes when trying to exit gnome. The screen flickers and goes black. There is no way to recover the system aside from hitting the power button.

Removing the framebuffer support from the kernel and recompiling it solves the problem of entering and exiting gnome but you miss out of the framebuffer support. Reading around it appears to be an issue with the nvidia-drivers. Currently there isn't a version in Gentoo portage that fixes the issue. The only work around is disabling framebuffer support for the moment.

Development Xorg.conf - Still needs refinement
