Subject: Re: [Linux-fbdev-devel] [PATCH] fb: hide cursor in graphics mode

Xserver Xfbdev (kdrive) uses linux framebuffer in graphics mode. It doesn't
need the text mode cursor, it's a bit annoying to have it there sitting in a
corner. This patch disables the cursor even when in graphics mode.

The testing is done on kernel version 2.6.18. This version should be
applyable on 2.6.28.4.
