From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.6) Gecko/20040120 Description of problem: On installation of FC2 my Xorg installation was configured to use the svga driver. That's the wrong selection for my "Radeon IGP 340M" hardware. I manually edited /etc/X11/xorg.conf, replacing "svga" with the correct "radeon" driver and all is well. Version-Release number of selected component (if applicable): 10.0-5 How reproducible: Didn't try Steps to Reproduce: 1. Install Fedora Code 2. 2. Note incorrect driver specified in config file. Actual Results: Two problem were observered as results of the incorrect driver selection: 1. Distorted screen on transition from text to graphical modes. 2. Complaints of not enough MTRRs (the svga driver likes to have a lot of distinct memory regions). Expected Results: Should see no problem entering or using the graphical interface. Additional info: This is on a Compaq Presario 2570us notebook machine. In RHL v9 the svga driver was correctly selected for this same chipset because the radeon driver did not yet support the hardware. A year later radeon_drv.o does drive the 340M (and provides 2D acceleration). Perhaps the installer has not been updated to make the association between the controller and the radeon driver? # lspci 01:05.0 VGA compatible controller: ATI Technologies Inc Radeon IGP 340M I selected the anaconda component per the instructions on the Bugzilla page. Note, though, that I did a text install ("linux text" from bootable FC2 CD #1).
Oops! Re-reading my bug report I see that I typed "svga" several times rather than the correct "vesa". When reading the above report, note that it was the "vesa" driver that was selected for my hardware by the FC2 installer. This is a snippet from xorg.conf, as configured by the FC2 installer: Section "Device" Identifier "Videocard0" Driver "vesa" VendorName "Videocard vendor" BoardName "VESA driver (generic)" EndSection Still, though, the wrong driver was selected for my I340 hardware. Sorry for the confusion.
The hwdata package has been updated in rawhide with fixes for many ATI chipsets. Please update to the rawhide hwdata package and see if it detects your chip properly now. If the problem remains, reopen the report and attach your X server log file or the output of "lspci -n", so we can get the correct PCI device ID to make the mapping. Closing as "RAWHIDE".
