I'm using X.org 6.8.2-r6 on a kernel 2.6.14-r5, with an Intel i855 video card. On a previous 2.6.12 kernel I was using framebuffer consoles with no problem whatsoever. After upgrading to 2.6.14-r5 (keeping the old .config as a base), frame buffer consoles still work perfectly, but after starting X.org they become unusable, flickering as if vertical or horiz frequency is somehow wrong. I need pointers to debug this trouble...
Please post "emerge --info" output to every bug that you file. Please say which framebuffer driver you are using. Please reproduce the problem on the latest development kernel (currently vanilla-sources-2.6.15_rc7)

Perhaps I have an additional input. This is the output from the boot of kernel 2.6.12: Dec 24 10:29:10 raistmobile vesafb: Intel Corporation, Intel(r)852MG/852MGE/855MG/855MGE Graphics Controller, Hardware Version 0.0 (OEM: Intel(r)852MG/852MGE/855MG/855MGE Graphics Chip Accelerated VGA BIOS) Dec 24 10:29:10 raistmobile vesafb: VBE version: 3.0 Dec 24 10:29:10 raistmobile vesafb: hardware doesn't support DDC transfers Dec 24 10:29:10 raistmobile vesafb: monitor limits: vf = 0 Hz, hf = 0 kHz, clk = 0 MHz Dec 24 10:29:10 raistmobile vesafb: scrolling: redraw Dec 24 10:29:10 raistmobile vesafb: framebuffer at 0xe8000000, mapped to 0xdf980000, using 1536k, total 16192k This is from 2.6.14 Dec 24 19:45:26 raistmobile vesafb: Intel Corporation, Intel(r)852MG/852MGE/855MG/855MGE Graphics Controller, Hardware Version 0.0 (OEM: Intel(r)852MG/852MGE/855MG/855MGE Graphics Chip Accelerated VGA BIOS) Dec 24 19:45:26 raistmobile vesafb: VBE version: 3.0 Dec 24 19:45:26 raistmobile vesafb: VBIOS/hardware doesn't support DDC transfers Dec 24 19:45:26 raistmobile vesafb: no monitor limits have been set Dec 24 19:45:26 raistmobile vesafb: scrolling: redraw Dec 24 19:45:26 raistmobile vesafb: framebuffer at 0xe8000000, mapped to 0xdf980000, using 10240k, total 16192k Note the different monitor limits line... Does this make any sense ?
Please confirm the bug exists in the latest kernel, currently gentoo-sources-2.6.15
(In reply to comment #6) > Please confirm the bug exists in the latest kernel, currently > gentoo-sources-2.6.15 I was stuck with gentoo-sources-2.6.13-r5 since everything higher gives me this kind of problem too. I upgraded to 2.6.15-r1 and the problem is still here. I have a nvidia card, using vesa-tng as a framebuffer console driver. Symptoms: the console is fine, I startx, switch back to console and it's unreadable. fbgrab image is fine though. I took a picture here: http://ttk22.free.fr/vesafb-tng.jpg ... If I close the lid, and open it again the console is back to the normal state. (Ps: am I posting in the correct bug ?)
(In reply to comment #7) Seems like it was the same bug: http://bugs.gentoo.org/show_bug.cgi?id=113408 Adding nocrtc works for me.
