Package: discover1-data
Version: 2.2006.10.29
Please note that this bug was originally opened for the Ubuntu 6.10 OS at
https://bugs.launchpad.net/bugs/72446 for a different version of the
package, but since the ubuntu package is based on Debian, I believe I
should report this bug and its suggested fix at Debian as well.
The S3 ProSavageDDR K4M266 (PCI device id 5333:8d01) is one of the devices
supported by the xorg 'savage' driver. However, the /lib/discover/pci.lst
from
the discovery1-data package lists the kernel module to load as 'unknown'
instead of 'Server:XFree86(savage)', as it should be.
This causes the video driver to fall back to 'vesa' upon discovery, since as
said before, there is no kernel module specified for this device on
/lib/discover/pci.lst.
I've got the 'savage' driver to work for this graphics chip on my system by
simply changing the 'vesa' line on /etc/X11/xorg.conf to 'savage'. A side
effect of the discovery of this device not working seems to be that I also
have
to explicitly specify the hsync and vrefresh ranges of my laptop's monitor
in
order to be able to work with the native 1024x768 resolution, whereas when
detection works (i.e. edited pci.lst) the native 1024x768 resolution works
without having to specify any particular hsync and vreferesh ranges in
xorg.conf.
* Here's my suggestion to what needs to be done:
replace the following line on /lib/discover/pci.lst:
53338d01 video unknown 86C380 [ProSavageDDR K4M266]
by:
53338d01 video Server:XFree86(savage) 86C380 [ProSavageDDR K4M266]
which simply means replacing 'unknown' by 'Server:XFree86(savage)'
* Suggested fix (pasted patch)
