Re: [sabayon-dev] Latest Limbo update screw up tty1 cuz KMS radeon being forced
Hi, I was able to reproduce the issue Joost mentioned. I was misleaded in believing that x-setup could have been the cause, since I reproduced the issue by deleting /etc/gpu-detector.conf and rebooted forcing x-setup to rewrite xorg.conf. Instead it turns out that the latest linux-sabayon version on Limbo (as of yesterday) had the: CONFIG_DRM_RADEON_KMS=y option in its configuration, that apparently auto loaded the radeon.ko driver, causing the conflict with fglrx. Today I have updated my kernel and to version: sys-kernel/linux-sabayon-3.4-r6 Which turns off that option: zcat /proc/config.gz | grep RADEON_KMS # CONFIG_DRM_RADEON_KMS is not set The radeon.ko module isn't auto loaded anymore so the issue is no more. But I now wonder if the suggested procedure to replace fglrx with radeon for newly unsupported AMD cards, on entropy notice board, is enough to load radeon.ko, or if the module has to be explicitly loaded by editing /etc/conf.d/modules.

Re: [sabayon-dev] Latest Limbo update screw up tty1 cuz KMS radeon being forced
I can confirm that with latest kernel bump (sys-kernel/linux-sabayon-3.4-r6 from Limbo) the issue is now resolved. The problem was exactly as pointed out by Lorenzo.

radeon.ko should be loaded automatically. Quick test, is 3D working? What's inside Xorg.0.log? -- Fabio Erculiani

On the FGLRX side everything is back to what was normal. xbox-360 joost # lsmod | grep radeon xbox-360 joost # lsmod | grep fglrx fglrx2579795 123 On Thu, Jul 19, 2012 at 6:19 PM, Fabio Erculiani lx...@sabayon.org wrote: radeon.ko should be loaded automatically.
