[gutsy tribe 2] Live CD fails to initialite AGP on ATI Mobility 9600

[Miguel Martinez]

When booting from a gutsy tribe 2 CD (md5 sums checked on download and CD), hardware detection will fail to:
* Set the correct resolution of the machine (1280*800)
* Initialite DRI
* see bug #122652 (garbled lines on screen)

My hardware is a Dell Inspiron 8600 laptop, with a Pentium M processor and a ATI Mobility Radeon 9600 Pro Turbo, which has had hardware acceleration since the Edgy pre-releases.

Inspection of /etc/X11/xorg.conf will reveal that, although DPMS is chosen for the monitor, the maximum resolution allowed is 1024*768. Adding "1280x800" to the display subsection fixes it. However, and regarding hardware DRI, I copy-pasted the ati section from my working Feisty ati config (just in case) and restarted X with Ctrl+Alt+Backspace. However, I got no direct rendering. Grepping EE and WW from /var/log/Xorg.0.log yields the following:

ubuntu@ubuntu:~$ grep WW /var/log/Xorg.0.log
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
        (WW) The directory "/usr/share/fonts/X11/cyrillic" does not exist.

        (EE) xf86OpenSerial: Cannot open device /dev/input/wacom
        (EE) xf86OpenSerial: Cannot open device /dev/input/wacom

Modprobing ati-agp and restarting X didn't help.

Hi Miguel,

Thanks for reporting this bug, and for reporting on the existing report for the garbled lines bug. The resolution mis-detection bug is well reported elsewhere, so for this bug let's focus on the DRI initialization issue.

Can you please attach your /var/log/Xorg.0.log, /etc/X11/xorg.conf, and output from lspci -vv?

[Miguel Martinez (el-quark)]

I'm attaching xorg.conf. I'm puzzled to see an empty "Files" section and no modules section at all. Wow. I'll be attaching the log and lspci -vv in the following posts. It seems I'm unable to make multiple attachments in a single post.

[Miguel Martinez (el-quark)]

Finally, here's the output of lspci -vv. I issued the command with sudo because otherwise I wouldn't get the capabilities.

[Martin-Éric Racine (q-funk)]

This should probably be reassigned to xserver-xorg-video-ati since an ATI mobility clearly is not a Geode GX/LX.

Hi Bryce,

I have some interesting news. I dist-upgraded to Gutsy last friday (after removing all local packages and assuring ubuntu-desktop was installed) and I was surprised when a reboot left me with DRI working fine via the radeon driver. Of course, I still suffered bug #122652, which makes me use fglrx, but well. I'm currently burning a live Tribe-3 CD and will check if booting from the CD gives me DRI. On a side note, the automatically generated xorg.conf has an empty "files" section. Is it intended?

[Miguel Martinez (el-quark)]

OK, I've tested and the tribe 3 live CD still gives me no DRI, and I'm getting the same AGP messages. Is there anything you would like me to do or check?

[Miguel Martinez (el-quark)]

Hi Bryce,

Could you tell me when a new tribe CD is released with xserver-xorg-video-ati 6.6.193 so I can test it again? Or maybe with some time to make sure if the CD will work OK with Dell Inspiron 8600's?

[Timo Aaltonen (tjaalton)]

Miguel: 7.10beta is out, please try that.

[Miguel Gaspar (ghaspias)]

With an ATI Radeon Mobility M7 (7500), the gutsy beta desktop live cd still has this problem:
        (EE) RADEON(0): [agp] AGP failed to initialize. Disabling the DRI.
        (EE) AIGLX: Screen 0 is not DRI capable
and
        (WW) RADEON(0): [agp] AGP not available
        (WW) RADEON(0): Direct rendering disabled

For me, unloading and reloading radeon (`sudo rmmod radeon && sudo modprobe radeon`) as sugested in Xorg.0.log:

>(WW) RADEON(0): [agp] AGP not available
>(EE) RADEON(0): [agp] AGP failed to initialize. Disabling the DRI.
>(II) RADEON(0): [agp] You may want to make sure the agpgart kernel module
>is loaded before the radeon kernel module.

solves _this_ problem, and gets me direct rendering. (How can I check / change the load order?)

Also take a look a bug #144077.

[Miguel Martinez (el-quark)]

I recently downloaded and burned the Gutsy final DVD for my girlfriend and, while testing that it was working OK, I still didn't have any acceleration available. However, I must admit I didn't do any kind of checks whether it was the same issue. I don't currently have that DVD, but I plan on downloading the live CD of gutsy final. I will keep you informed

Another good point of my girlfriend wanting to test ubuntu is that she has an ATi 7500 VE (or something like that), so I will be able to report if this issue also appears on her computer.

As a sidenote, the 6.8 branch of the radeon driver now correctly sets my resolution.

[Bryce Harrington (bryce)]

Miguel,

It would be great if we could hear your results of testing the Hardy release candidate. A lot has improved in -ati since this bug was filed, and it would be great to hear whether the issues you identified are now solved.

[Miguel Martinez (el-quark)]

Dear Bryce,

I downloaded and burnt the Hardy RC live CD yesterday and it seemed to work fine. I only tested with glxgears, since I have to do some editing in order to get compiz working on my card. Although I didn't copy /var/log/Xorg.0.log, I'm 99% sure grepping EE only gave the first (inocuous) lines:

ubuntu@ubuntu:~$ grep EE /var/log/Xorg.0.log
        (WW) warning, (EE) error, (NI) not implemented, (??) unknown.
        (II) Loading extension MIT-SCREEN-SAVER

I didn't see any other warnigs or errors regarding agp. If you think this is enough to mark as fixed, feel free to do so. Else, if you want more info, don't hesitate to ask. Oh, and, yes, -ati has improved a lot. Now testing your patched 6.8 deb, by the way.

[Bryce Harrington (bryce)]

Thanks sounds good, closing as fixed!
