Seems like there have been some changes on that subject in time. Keep |
| 29 |
in mind, up until a few months ago I was running Windows7 on my |
| 30 |
workstation. I'm not new to linux, as I've been using linux on servers |
| 31 |
since a very long time, but the whole X stuff is kinda new for me. |
| 32 |
|
| 33 |
In the past I always experimented with linux in dual boot, and I vaguely |
| 34 |
recall that there were (or are?) different kinds of video drivers on |
| 35 |
linux. You had the drivers provided by the kernel, the drivers of Xorg - |
| 36 |
like xf86-video-ati - and third party drivers like ati-drivers fglrx. |
| 37 |
And now there's kms too, which I understand is not a driver, but a means |
| 38 |
for the kernel to setup the driver itself (resolution, color depth). |
| 39 |
|
| 40 |
So, if I now use the kernels radeon driver, i could use kms, but cannot |
| 41 |
use xf86-video-ati or fglrx, if I use xf86-video-ati or fglrx, I cannot |
| 42 |
use kms? |
| 43 |
|
| 44 |
It would be great if someone could link me to some reading material on |
| 45 |
that subject. Something that explains, the difference between kernel |
| 46 |
video drivers, framebuffer console, Xorg video drivers and 3rd party |
| 47 |
drivers. |
