Re: [opensuse] Radeon HD 6450
On 2012/03/11 19:08 (GMT-0400) Michael Fischer composed:

FWIW, this is all persuant to my threads "12.1 installation failure"
and "Video cards and 12.1" of the past few days.

What were you using last before 12.1 (or now?)?

Card is Radeon HD 6450

What rv is that (available from lspci output)? Is a built-in part of the motherboard?

Got the darn thing to install.

At the initial reboot, it gave up on graphics saying something
like (sorry I didn't copy it down) "couldn't find a graphical
interface". I proceeded as follows:

1) chmod +s /usr/X11/bin/Xorg
2) cp xorg.conf.install xorg.conf

I think this does little but try to specify that the native FOSS driver for your video chip will not be used.

3) startx (this got me started into LXDE - specified during install)

See also the tail of /etc/permissions.local.

hwinfo (the graphical'd version in yast) suggests that I've got a display
of "ATI VGA compatible controller" whose driver is "Radeon". Indeed
lsmod(8) shows the radeon driver loaded. It certainly is not mentioned
in the xorg.conf. And fbdev (nor indeed 'fb' anything) is shown by lsmod.

Xorg.0.log speaks repeatedly of vesa, but no module with 'vesa' in it is
currently loaded by the kernel. (perhaps that's not the right place to
look?)

I notice something about a SAX3, but the repo is not displayed
in the yast2 repository list. How to add it?

Suggestions more than welcomed about all this.

1-Put /var/log/Xorg.0.log where list subscribers can see it, preferable an upload that won't get wrapped to your own personal web space or http://susepaste.org/ or http://pastebin.com/ or similar.

2-Read:
http://en.opensuse.org/SDB:ATI_troubleshooting
http://en.opensuse.org/SDB:Radeon
http://en.opensuse.org/openSUSE:Bugreport_X#How_to_test_the_latest_Xorg

3-consider other mailing lists where those with more experience with your video chip might be focusing their attention:
opensuse-kernel
opensuse-xorg

4-uploading y2logs might also prove helpful before this is resolved: http://en.opensuse.org/Bugs/YaST#I_reported_a_YaST2_bug.2C_and_now_I_am_asked_to_.22attach_y2logs.22._What_does_that_mean.2C_and_how_do_I_do_that.3F

I'm off to experiment with things like specifying "Radeon"
in xorg.conf but... *sigh*

Managing xorg.conf by hand can be unwieldy. An alternative that's less succeptible to parse errors is using /etc/X11/xorg.conf.d/, specifically in most cases: 50-device.conf, 50-monitor.conf, 50.screen.conf. http://lists.opensuse.org/opensuse/2012-03/msg00388.html has an attachment with an example/minimal use of these three files either individually, or combined into xorg.conf.

I've sometimes found that attempting use of these three files will lead to loss of keyboard and mouse if /etc/X11/xorg.conf.d/90-keytable.conf does not exist. Main thing I can tell it does is specify use of evdev input device driver.

I have sometimes found, never having used a video chip even close to yours (AFAICT), that a fourth file in xorg.conf.d/ can sometimes be helpful (it disables compositing) at least for troubleshooting:

#70-composite.conf
Section "Extensions"
Option "Composite" "Disable"
EndSection

I should say that the current situation sometimes leaves window content
sort of garbled on movement. Not good for real usage, though it might
get me though some debugging.
