[CLE266]Since upgrade from jaunty to karmic, one of two thin clients' login broken (AIGLX problem).

[Jon Coldewey]

Since upgrade from jaunty (ubuntu 9.04) to karmic (ubuntu 9.10), one of my two thin clients using ltsp no longer permits logins, even though the thin client boots fine and serves up the login screen. It looks like a display driver error or authentication error. The machine works fine with karmic when directly running live-CD (via usb-stick; it is a diskless mini-itx via based thin client). It worked fine under jaunty.

Once I enter the user name and then password, the wait icon appears, but after approx 2/3s time the display reverts back to the login screen. Login on the other thin client hardware using same credentials works fine.

It appears this is a duplicate of bug: 463369, see:

"https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/463369"

Sorry for the unnecessary report/post.

Jon

[Tormod Volden (tormodvolden)]

Please attach your Xorg.0.log and dmesg output, so we can verify if this is a duplicate or not.

[Jon Coldewey (coldewey)]

OK, sorry, but I may need some help in obtaining the requested logs: on jaunty I had the thin clients set up to send their logs to the server in specified client subdirectories, using syslog-ng. Karmic uses rsyslog by default, and I haven't yet figured out how to open this up for external logging. Jon

[Tormod Volden (tormodvolden)]

I am not so familiar with the LTSP setup, but can you log in as a local user on a text console? Then you can use scp to copy the files to another computer. Note that the X server does not use rsyslog anyway.

[Jon Coldewey (coldewey)]

Thanks, I will set something up and obtain the logs. It may take some time,
because I only have intermittent access (I can only boot into the karmic
system when this does not disturb regular operation. I re-instated jaunty on
another partition to maintain regular operation).

If you can attach the Xorg.0.log and dmesg output from booting the Karmic live CD usb stick, it would help also. And try to run glxinfo on it.

By-the-way: specifying XSERVER as vesa leaves all screens black.

Interestingly, using the specification of XSERVER = openchrome, I had a very brief glimpse of the user desktop from the server, before I was thrown back to the login screen. While I cannot sucessfully log into gnome desktop from the ltsp terminal, I can login to xterm and lauch X applications such as firefox, etc from there!

Thanks. For the future, please attach the logs instead of pasting them into the comments.

You are using the -openchrome driver (with the "via" 3D driver) so it is certainly not a radeon issue here.

I noticed this in the LTSP X log, but I do not know if it causes any harm:

[config/dbus] couldn't take over org.x.config: org.freedesktop.DBus.Error.AccessDenied (Connection ":1.7" is not allowed to own the service "org.x.config.display7" due to security policies in the configuration file)

The xsession-errors are difficult to read, but I wonder if this:

Trying again with indirect rendering:
Checking for texture_from_pixmap: gnome-screensaver: Fatal IO error 11 (Resource temporarily unavailable) on X server 192.168.0.110:7.0.

means glxinfo is bombing out when tried with indirect rendering? Please try "glxinfo -i" on the live CD.

[Tormod Volden (tormodvolden)]

Instead of the live CD, you can of course use the xterm which you mention in comment 15.

[Jon Coldewey (coldewey)]

glxinfo and glxinfo -i don't work in the xterm ltsp login session. I get an error:

"name of display 192.168.0.110:7.0
X Error of failed request: BadRequest (invalid request code or no such operation)
Major Opcode of failed request: 138 (DRI2)
Minor Opcode of failed request: 1 (DRI2Connect)
Serial number of failed request: 19
..."

glxinfo -i within an Xsession on the live-CD system is interesting in that it immediately kicks me out of the session to a logon screen, and corrupts the video on all the VTs. That behaviour is identical to what happens, when the netbooted ltsp client attempts to login from the ldm login screen into the server X session. Then also, the client side virtual terminals get a corrupted screen.

Jon

[Jon Coldewey (coldewey)]

PS: I get the X Error BadRequest also in an xterm under jaunty, so that seems to be a sane response:

jon@sun:~$ glxinfo -i
name of display: 192.168.0.110:7.0
X Error of failed request: BadRequest (invalid request code or no such operation)
  Major opcode of failed request: 138 (DRI2)
  Minor opcode of failed request: 1 ()
  Serial number of failed request: 19
  Current serial number in output stream: 19

Jon

[Tormod Volden (tormodvolden)]

(To correct myself, this is using the "unichrome" 3D driver)

There should be no DRI2 support on these drivers/cards, so I guess a DRI2 request should fail, unless it is a "is-there-DRI2" probe request. Anyway, glxinfo -i should not fail like that.

Just to make sure this is still an issue in latest upstream versions, can you please try the openchrome driver from https://launchpad.net/~xorg-edgers/+archive/drivers-only

[Jon Coldewey (coldewey)]

Tormod, do I need to install this updated driver in the ltsp chroot (client), on the server (host), or both?

Although, I guess it shouldn't do any harm installing them in both, as the server doesn't have any openchrome hardware.

Jon

[Tormod Volden (tormodvolden)]

In the LTSP chroot. The graphics driver (the X server) is running entirely on the LTSP client. Only the X clients (applications and window manager) are running on the LTSP server, and send drawing requests to the X server (and receive keyboard/mouse events).

[Jon Coldewey (coldewey)]

I have now installed the upstream openchrome driver in the chroot and updated the image. There is no change in the bahaviour of the affected thin client.

Jon

[Bartosz Kosiorek (gang65)]

Attach your /var/log/Xorg.0.log file.
If you can from after reproducing this issue.

[Jon Coldewey (coldewey)]

Bartosz, I have already (unfortunately pasted into the comments, instead of attached), please see thread above. It is "Xorg.7.log" because it originates from the ltsp client. I will attach it properly for reference. Jon

[Jon Coldewey (coldewey)]

I'm not sure this is an issue with the openchrome driver. I copied the openchrome driver from jaunty ltsp to the karmic ltsp, well expecting it wouldn't work at all, because it was compiled for a different kernel. But the system boots up and shows the same fault symptoms as with the current and upstream openchrome video drivers, Xorg.7.log attached.

Jon

[Jon Coldewey (coldewey)]

.. then again, the terminal that _does_ work, uses the vesa driver!

[Bartosz Kosiorek (gang65)]

Hello.
Try to run Karmic with kernel from Jaunty (2.6.28).

Try also disable DRI by adding editing xorg.conf file:

    Section "Module"
       ...
       Disable "dri"
       ...
    EndSection

[Jon Coldewey (coldewey)]

I created an xorg.conf file (there is no xorg.conf by default) in /opt/ltsp/i386/etc/X11/, as suggested above, disabling DRI . This represents a workaround to the problem, I now managed to log into the karmic ltsp server and I am accessing launchpad.net from within. The only disadvantage to jaunty, that I have observed so far, is for instance loss of transparency in gnome-terminal windows. Thanks, Bartosz

Jon

[Bartosz Kosiorek (gang65)]

Hi.
Try to enable DRI and disable AIGLX.

You can disable AIGLX and the compositing extension by amending your /etc/X11/xorg.conf like this:

Section "ServerFlags"
Option "AIGLX" "off"
EndSection

Section "Extensions"
Option "Composite" "Disable"
EndSection

[Jon Coldewey (coldewey)]

Bartosz,

That works as well.. I have removed the section from xorg.conf, that disabled DRI, and instead switched off AIGLX and disabled the compositing extension, as proposed.

Jon

[Bartosz Kosiorek (gang65)]

Add the to the Section "Device" following lines:

Option "XAANoOffscreenPixmaps"

Next, find the Section "ServerLayout" for your graphics card, and add the following:
Option "AIGLX" "true"

Try also enable compositing extension.

[Bartosz Kosiorek (gang65)]

Can you check the output of ~/.xsession-errors for anything interesting (with DRI and AIGLX enabled)?

[Jon Coldewey (coldewey)]

OK.. wee problem related to my ignorance in configuring xorg.conf from scratch: at least under LTSP, xorg.conf is generated on the fly when the thin client boots up. I have created a custom xorg.conf for the various parameters outlined in this thread, but this does not include a "ServerLayout" section for the graphics card. How do I ensure the right naming convention for my card, so that we are sure it is actually read?

Jon

[Bartosz Kosiorek (gang65)]

Sorry.
My mistake.
There is no ServerLayout.

Enable AIGLX and add to the Section "Device" following lines:

Option "XAANoOffscreenPixmaps"

[Dolganov Victor (victor-dolganov)]

I have the same problem with openchrome on one karmic client and with kde 4.3 on LTSP server. If KDE 3.5 on LTSP server it works fine. On other ltsp client with openchrome it works with both KDE 4.3 and KDE 3.5.

[Dolganov Victor (victor-dolganov)]

Option "XAANoOffscreenPixmaps" in config helps for me.

[gcc (chris+ubuntu-qwirx)]

I found the same problem with an Aleutia E2 (VIA Eden CX700/VX700, openchrome), lucid, LTSP thin client.

It appears to be caused by this bug: https://bugs.launchpad.net/ubuntu/+source/gnome-session/+bug/673072

Note that it usually, but not always, fails to log in from ldm on the LTSP client. The session crashes after about 3 seconds of spinning wheel wait cursor, and I get kicked back to the login screen.

There is a workaround that you could try in that bug report: force gnome to use metacity instead of compiz as the window manager.
