The reason I discovered the solution was that I looked through the |
| 13 |
/var/log/Xorg.0.log file. This file is usually 95+% boring technical |
| 14 |
detail. Near the top of the log file is a section that says... |
| 15 |
|
| 16 |
[ ??.???] Markers: (--) probed, (**) from config file, (==) default setting, |
| 17 |
(++) from command line, (!!) notice, (II) informational, |
| 18 |
(WW) warning, (EE) error, (NI) not implemented, (??) unknown. |
| 19 |
|

I suggest viewing the log file with your favourite editor, and doing a |
| 21 |
case-sensitive search on the 2 strings "(EE)" and "DRI" (without the |
| 22 |
quotes). That was what tipped me off to the fact that... |
| 23 |
a) there was a problem with DRI |
| 24 |
b) what file Xorg was looking for that it couldn't find |
| 25 |
|
| 26 |
Knowing that info, you can put the appropriate entries into the |
| 27 |
VIDEO_CARDS variable in make.conf. Intel is a bit weird; it wants |
| 28 |
both intel and the major driver version. E.g. for my older desktop... |
| 29 |
|
| 30 |
VIDEO_CARDS="i915 intel" |
| 31 |
|
| 32 |
...and for my newer HTPC machine... |
| 33 |
|
| 34 |
VIDEO_CARDS="i965 intel" |
| 35 |
|
| 36 |
Then re-emerge mesa. If Portage asks you to change some USE flags as |
| 37 |
part of the process, do so unless it causes problems. Once mesa is |
| 38 |
rebuilt, run... |
| 39 |
|
| 40 |
emerge -pv --newuse --deep world |
| 41 |
|
| 42 |
This will give a "pretend" run. If it looks OK, run it for real... |
| 43 |
|
| 44 |
emerge --newuse --deep world |
| 45 |
|
| 46 |
Again, portage may suggest changing some flags. I ended up having to |
| 47 |
rebuild xorg-server and one lib. After that, run revdep-rebuild. And |
| 48 |
if you're changing the card type, you'll have to make the corresponding |
| 49 |
changes in the kernel via "make menuconfig", rebuild the kernel, and |
| 50 |
reboot. If you get lost, ask here. Copy the relevant error messages |
| 51 |
from your Xorg.0.log file to help track down the problem. |
