[Mageia-dev] gma500 display driver problem with Mageia 2 alpha

Mon Jan 2 13:21:24 CET 2012

Hi
+
+I got couple of years old Nokia booklet which has gma500 gpu and 
+1280x768 panel. I installed i586 version of Mageia 2 alpha2. 
+Installation went fine but on next reboot the ui failed to show up.
+
+I went to drakconf console and there the display drake identified the 
+card ok and suggested using "Poulsbo US15W (gma500)" driver.
+That will install dkms-psb module that will howeve fail to load with 3.0 
+kernels.
+
+If I force the vesa mode in drakconf, then the display works ok in 
+1280x768 mode. (Thought not the world fastest display).
+
+Another option is to use fbdev drivers that to my understand uses
+new psb_gfx module that is available for 3.2 kernels.
+(/lib/modules/3.2.0-desktop586-0.rc7.2.mga2/kernel/drivers/staging/gma500/psb_gfx.ko.gz 
+on latest mageia devel kernel)
+
+With the fbdev kernel, I could however select the 800x600 resolution in 
+maximum with drakconf. Any idea what should be changed in drakconf
+to enable the psb_gfx/fbdev driver by default with gma500 and to allow
+to select higher resolution like 1280x768?
+
+At the moment I have updated all packages to latest versions in devel 
+repositories.
