Look directly into /lib/firmware/radeon/ and make sure you do not have |
| 20 |
a typo somewhere. |
| 21 |
|
| 22 |
Building directly into the kernel is a really good idea for video drivers. |
| 23 |
|
| 24 |
Another tool you may want to check out, is Rich0's kernel crash dump page:: |

Last, when all else fails and is actually quite easy is to find a |
| 30 |
liveCD/DVD, from any distro that boots your lappy with the radeon driver |
| 31 |
that works. Then you parse about to find the one it uses. Some of these |
| 32 |
drivers are very close in the components and vendor card vendors have |
| 33 |
a 'malaise' of dis information surrounding the exact specs of the video |
| 34 |
components in there hardware, particularly laptop and tablet vendors. |
| 35 |
|
| 36 |
|
| 37 |
Just keep looking around, trying different ones out and something will |
| 38 |
work, eventually. |
| 39 |
|
| 40 |
'lspci -k' show video driver details use on a generic livedvd booted system. |
| 41 |
|
| 42 |
A livedvd was created to give away at a recent california conference but I |
| 43 |
did not see it posted anywhere on the Release Engineering project pages. |
| 44 |
There are other gentoo derivative distros with livedvd you can bootup |
| 45 |
to help find the correct driver. |
