Re: [gentoo-user] Colors corrupted in X after returning from text console
On Wed, Oct 21, 2009 at 10:59:12PM -0400, Albert Hopkins wrote KMS drivers and framebuffer console drivers are different and AFAIK mutually exclusive. The boot parameter to disable KMS would be, e.g., i915.modeset=0 I don't want to disable KMS, I want to disable framebuffer, and I simply cannot do so with the i915 driver enabled... period. end of story. It is automatically enable in make menuconfig. The option is -*- rather than [*]. I've tried nofb in the lilo append line, and manually unsetting all the FB_CONFIG* parameters in .config with vim and rebuilding, but it still comes up in framebuffer mode. I'll have to wait for the next kernel updates, I suppose. I don't want to play with ~x86. -- Walter Dnes waltd...@waltdnes.org

[gentoo-user] Colors corrupted in X after returning from text console
Some people like the nice crisp text of true console mode. Many can't stand surfing with a textmode browser. Count me in both groups. So I switch back and forth a lot. This email is being composed in a true text console (80 columns x 48 rows; but that's another story). I flip to X for surfing/spreadsheets/etc. When I do, I find that the colours on my current machine's display are corrupted. Clicking on a window will reset most of the colours, but the window title-bar still looks like colour confetti. Background info...
