I am new to sabayon and am having an annoyance with the ati drivers it uses. I have played with the various drivers (proprietary, radeon, and radeonhd) on other linux distributions (opensuse and linuxmint) and have the same issue. I'm stuck on how to get it fixed and any help would be appreciated.
Here's my issue:
I receive periodic flashes when using Gnome shell (no issues in kde, or lxde). It isn't timed(ie. like every 30 sec), but varies (can be as low as 10 sec, but as high a 45-50 sec). This flash causes whatever I am typing to quit accepting input requring me to click in the text box and continue. In opensuse It would do the same, but every 5 minutes or so it would log me completely out of gnome.
The Xorg, dmesg, and messages logs show nothing new after the flash (maybe flicker is a better description?). This issue does not exist when in fallback mode (in both opensuse and linuxmint... not tested in sabayon). I guess I should say it doesn't happen under windows either.
