Issue with Radeon driver

[Vitoriung]

My card is radeon HD4800 and after recent update the flgrx driver stopped supporting my card so I switched to radeon.
Now xdm doesn't start on boot. I have to restart xdm 5 times to finally get the login screen (1st time I get black screen and 3 times I get mishmashed picture), after that I am up and running, but it's annoying to do that on each restart.


I did following:

Code: Select all

equo install x11-drivers/xf86-video-ati
equo remove ati-drivers ati-userspace
rm /etc/X11/xorg.conf
eselect mesa set auto
reboot


also from Joost's blog (https://joostruis.wordpress.com/2011/01 ... -catalyst/) step 4 and 5:

Code: Select all

Step 4: Add a custom parameter that enables KMS (Kernel Mode Setting)
Edit /etc/default/grub and add radeon.modeset=1 to the GRUB_CMDLINE_LINUX_DEFAULT variable

Step 5: Regenerate your grub.cfg file:
grub-mkconfig -o /boot/grub/grub.cfg


I had a chat on IRC with Sabayon guys, they told me everything is working fine, just XDM starts too soon. So I tried to change the xdm script from boot to default without any success.

Any idea what could go wrong?
Can you also advise in the mean time where to put the aditional script I made that would restart the xdm without me having to login to terminal as root and running it manually?

Not sure if I can mark this as resolved, I figured out how to make the script running just after xdm starts.

I put following script into /etc/init.d/ and made it run in default init:

/etc/init.d/xdmrst

Code: Select all

#!/sbin/runscript

depend() {
     after xdm
     }

     start() {
      for i in {1..1}
      do
            /etc/init.d/xdm restart
      #sleep 5
      done
      } 


Before it was a loop {1..5}, but when this scripts runs immediately, only 1 restart is needed so no more delay at the start now, however I would call this not a solution, but rather a workaround.

I cheked my Xorg log on the first start of xdm:

There is one thing indicating xdm is starting too soon:

Need to restart xdm 5 times again to get the login screen.

Is there any way how to check why xdm starts too early? or perhaps some modules needs to be specified manually to load on boot?

[lxnay]

Add "radeon" to modules= variable inside /etc/conf.d/modules.
Example:

Code: Select all

modules="radeon"

[Vitoriung]

Add "radeon" to modules= variable inside /etc/conf.d/modules.
Example:

Code: Select all

modules="radeon"

Great that helped. Now I have issue with the blackscreen with mouse cursor. I have to restart xdm 1 time to workaround it.

Could that be an issue with lxdm, here is the log:
