 Posted: Tue Nov 20, 2012 8:51 pm Post subject: [Solved] X fails to start after upgrade |
 |
|
I recently upgraded to kernel 3.6.6 (this is built with genkernel with the arguments "all --menuconfig --splash=natural_gentoo splash-res=1024x768") and Xorg-server 1.13.0-r1 and I switched from the ati fglrx drivers to the open source radeon drivers (my ati chip is an RV710 and as far as I gathered, this is no longer supported by the new drivers).
Ever since my X no longer starts up. Here is some of the Xorg.0.log:
| Code: | [ 7695.011] (--) using VT number 7

I understand that KMS needs to be enabled. How do I do that with the genkernel?
Are there other obvious things I'm missing?

Q-collective,
A good outline for radeon drivers is located here
Just use make menuconfig to adjust your settings

If you use genkernel, then you can also use genkernel --menuconfig
If the radeon driver is built as module, you must ensure that it loads before X starts. This is typically done through /etc/conf.d/modules |

Switching on KMS in the kernel did indeed solve the issue (as well as probably removing the ati-drivers package from the system).
What helped me in particular was this radeon guide on the Gentoo wiki.
Thanks all |
