I get the following trying to run edubuntu live 64 bit. http://picasaweb.google.com/davmor2/UbuntuScreenshots/photo#5138745957617176562

This is not good at all.

Hi Dave, Please confirm that this only happens on edubuntu 64 bit, but ubuntu.

Could you please follow the instructions on https://wiki.ubuntu.com/X/Debugging and attach the appropriate debugging info. See under "Screen display corruption"

Dave Morley (davmor2) wrote :

Yes this bug is only on edubuntu Live. On the alternative cd the install was flawless and on Ubuntu, Xubuntu there was no error.

I shall add the Debugging info shortly.

Enclosed is the X0rg log file.

Please let me know if there is any other info you require.

I've been playing with various settings all evening and I have found a solution.

Once the first menu appears hitting F4 then selecting 1024x768 (my max res on this monitor) the process of get the desktop up is slower but I get a viewable screen. I can then install also.

Please try hardy alpha2.

Dave Morley (davmor2) wrote :

Same thing in Alpha 2/3. The issue also affects Ubuntu and Xubuntu but not Kubuntu. So we believe it may be an issue with gdm itself.

Please let me know if there is anything else I can help you with.

Just been doing some tests on my laptop using Ubuntu. (Laptop is a HP Pavillion DV9657EM) This has real problems in 64bit but works flawlessly in 32bit.

In 64bit I forever get no slpash screen and I always get the Xserver is in low res mode box appear. Also I notice that it isn't detecting the Nvidia GFX card that is on board.

In 32bit I get the correct resolution imediately and the screen is at 1440x900 which is correct. In this instance the nv module was correctly used.

I am therefore under the impression that it is the detection system used by 64bit that is at fault. (please fault my logic if you can :) )

This bug is still apparent in Alpha 4 candidate cds.

Up until this point this bug has only been reported as affecting Edubuntu 64-bit, but in your latest ISO testing report (http://iso.qa.ubuntu.com/qatracker/result/1279/195) you've marked it as applying to Ubuntu alternate. Can you please clarify?

sorry, I see now that in mid-January you reported this as affecting Ubuntu/Xubuntu as well. Ignore me then...

Steve I've altered the title to make it a bit more obvious hope that helps.

This is the lspci -vvnn on my main machine. This is the one that is pretty much okay running the nv driver only plays up when I install Nvidia Driver New via jockey.

I think this is a variant of https://bugs.launchpad.net/ubuntu/+source/usplash/+bug/147623.

There are several mentions of unusable livecd installs there dating back to feisty all involving nvidia 8xxx.

Dave Morley (davmor2) wrote :

Roger This also effects the other 2 type of nvidia cards I have to differing levels.

Roger E Critchlow Jr (rec) wrote :

Ah, I see. They're listed in the attached Xorg.log.0 and lspci outputs.

In the first Xorg.log.0 you attached, the NV xserver says:

(--) Chipset Unknown NVIDIA chip found

and the chip detected by PCI probe:

(--) PCI:*(1:0:0) nVidia Corporation GeForce 7100 GS rev 161, Mem @ 0xd0000000/24, 0xc0000000/28, 0xd1000000/24, BIOS @ 0xd2000000/17

isn't listed as supported by the NV server startup list.

The other two Nvidia chips you list:

01:00.0 VGA compatible controller [0300]: nVidia Corporation NV35 [GeForce FX 5900] [10de:0331] (rev a1) (prog-if 00 [VGA controller])
05:00.0 VGA compatible controller [0300]: nVidia Corporation GeForce 8400M GS [10de:0427] (rev a1) (prog-if 00 [VGA controller])

are both listed as supported by the NV xserver.

I wonder if that affects the differences in behavior you're seeing?

I also wonder why you're not seeing the problems reported in https://bugs.launchpad.net/ubuntu/+source/usplash/+bug/147623 with your GeForce 8400M machine.

On my laptop which is the 8400M machine if I run in 64bit I get no splash which is why I run 32bit on it.

In 32 bit there is no problems everything displays fine. It is only in 64 bit land where I get those issues.

My 64bit main pc's issue of black screen when the nvidia drivers were installed has been resolved (I bought a new monitor). This is the one that I have attached the log for above.
