I woke up this morning willing to edit a bit in my xorg.conf file, the video driver i wanted to chage from vesa to radeon. But i noticed that the file wasn`t like the other ones from my previous instalations, and had allready been edited ..by itself, with my ati driver, my mouse and scroll working. I rebooted, and when i came back to X, surprise, i had my vide card working, all the resolutions in place, my 1280x1024 working great. How could this have happen over night? I sware i didn`t do nothing in xorg.conf.

Well you do need to restart X for any changes to take effect.

Also X looks for and uses an xorg.conf file if it finds one in your current directory.

Many people have had a copy of xorg.conf in their /root/ directory and wondered why the changes they made had no effect each time they startx =)

Some video driver installers will edit the xorg.conf as part of the install... they should of course ask your permission though.

I think it was the Slackware fairy.

The morning is wiser than the evening. (Russian proverb)

It must have been, now i think it was the Slackware demon. I stopped X and logged off my user, and shut down my PC, now, when i try to start x again, it closes my monitor when it tries to show X. I left 1280x1024 resolution from my last use ( it worked fine ). And now it won`t start. I can`t understand what the hell is happening.

And now after a few reboots, it works. 1280x1024 on and works as a charm. This is so weird.

How do you log into X, graphical (init 4) or via command line (init 3)?
If it is init 4, add the line xrandr -s 1280x1024 in the file ./Xdefaults (if it doesn't exist, create it yourself)

If you start X via init 3, put that line in ./xinitrc.

Chances are that it will always start with that screen resolution (it worked for me).

If you install the video driver using the ati*run file, it automatically looks adjusts your xorg.conf file. They have some gui program the runs in X amdccb or something like that. Perhaps it does it also.

But, if you are using the radeon driver that comes with the kernel, or that from the gits, I don't think it adjusts your xorg.conf file. If this is case it must be fairy (or really friendly hacker).

Note if you are using slackware-current, you may not need an xorg.conf. Trying renaming it and starting X. If it works, look at /var/log/Xorg.0.log and see what driver its using.

I recently removed all keyboard and mouse related entries in xorg.conf and these still work well. I maintain control of which video driver is used (radeon or radeonhd) and so keep some options.

I user 12.2 not current. Didn`t install any driver. And still my xorg file just changes intself, sometimes it shows at 1280 sometimes it doesn`t. And i loggin in with command line startx.
