Bug Description

On 20090929.2 of ubuntu 64bit alternate.

Ltsp starts but you can not login under the only user on the system.
Login screens says Verifying password. Please wait.

Then it cycles back to the a-c-f1 messages and back to the login prompt.

p.s. had to redirect the i386 to amd64 in /etc/ltsp/dhcp.conf first

As a first step, could you try to run the following on the server?
sudo ltsp-update-sshkeys
sudo ltsp-update-image
and then restart the client?

Same for me.

There were some messages about corruption in squashfs:

failed to read block 0xb951c75

Ltsp-update-sshkeys and ltsp-update-image didn't help. The image seems to be broken.

screenshot of unreadable client desktop Edit (413.9 KiB, image/png)

I tried another client and now i/o errors don't appear even on the first device. Login works properly (for second unprivileged user as well).

But there is another huge bug - the X server mirrors the screen, so it's unreadable. Tried on Asus EEE PC 1000H and Lenovo 3000 N200.

Update:

Works for me. Do you have properly set network? With static IP address for server?

The bug with unreadable screen on client is caused by Nvidia drivers on server.

This affects Lucid as well. Login repeatedly fails as above. Updating the keys and the images did not help.

Confirmed on Lucid. I have ltsp-server 5.2.1-0ubuntu9 with 33 workstations working with an external DHCP service. We use dnsmasq (backported from Maverick because of the udhcpc bug). Two to three accounts end up not being able ot log in every time the lab is full.

Updating the keys did not help. Where should I look?
