Blank screen on Radeon IGP 320M

[sploo22]

I just got Gentoo installed on my HP ze4325 laptop. When I try to startx, it apparently works (no error messages) but the screen is blank. It even powers off - I saw the backlight disengage. It shuts down cleanly on Ctrl-Alt-Del and the Caps Lock etc. keys work, so I know it's not frozen. However, until I reboot the screen is totally dead.

I've tried both the Radeon driver and the framebuffer one. I also found this page (http://www.cybersym.com/pages/linux-ze4100.html) about a similar model and tried the XF86Config there, but no luck.

The video card is an integrated ATI Radeon IGP 320M. The man page for the radeon driver says it's supported, but... :(

Has anyone had any experience with these cards? Thanks in advance.

By the way, here's my XF86Config file. I'll post the log if anybody wants it.

Have you checked your X logfile for errors?

/var/log/XFree86.0.log

grep EE /var/log/XFree86.0.log

Well, I managed to get it working in framebuffer mode: I booted into Knoppix and copied the monitor frequencies down, set the driver to vesa and voila! Thanks anyway. :)

By the way, glxgears reports a frame rate of about 300fps. Is this good? bad? mediocre?

I doubt you will be playing any graphic intensive games anytime soon.

Best to keep looking for a solution for getting the 320M working properly.

Did you check at www.xfree86.org to see if they have anything on the 320M or the ATI support site. Perhaps ATI has support forums as Nvidia does.

According to the documentation at dri.sourceforge.net, 3D acceleration support for the IGP series was recently integrated into CVS. I don't usually do much graphics-intensive stuff, so I'll probably wait until it makes it into the official release.
