screensaver locks up X

Bug Description

Binary package hint: xorg

When the screensaver activates, the machine is unresponsive to keyboard or mouse and must be rebooted. Also, when the System->Preferences->Screensaver setup is activated, I can slide the "idle after:" bar with the mouse, but cannot click on anything else in the window. I can minimize/maximize the window normally, (there is a 1 second delay) but cannot click on any other buttons.

Additionally, after maximize/unmaximize all buttons and sliders are gone, except for the screensaver preview itself running in the "Screensaver Preferences" window. The "Close window" tooltip appears when I hover over the close, but the window refuses to close when I click on the "X". I can move the window normally, and all options work except for close. I am only able to terminate the "Screensaver Preferences" session by using the "Force misbehaving application to quit" app in the toolbar. I am up to date with all Jaunty patches so far.

Found something - the desktop had been randomly hanging every now and then so I tried uninstalling the NVidia version 180 closed source driver and the System->Preferences->Screensaver window now behaves normally. Unfortunately, the display is low resolution and looks crappy but if I have to, I will take this over the hang.

This is essentially the same root cause of another bug I filed where Evolution would hang on launch and sometimes corrupt the display. It also went away when I deleted the NVidia driver.

I am going to try with the older version 173 driver and see if it is as problematic. The version 180 driver is buggy to the point of being unusable.

Works a lot better with the 173 version.

Seems to be fixed! Thank you, release date is getting close and I was getting worried this would be forgotten.

Bug is still present in 180.44 with stock 9.04 kernel 2.6.28-11-generic.
Display looks and works fine until screensaver activates and is active for more than 15-20 minutes (brief intervals like 1-2 mins seem to not trigger the problem). Screensaver is set to prompt for password, and it does, but after logging in, keyboard is unresponsive, CTRL-BACKSPACE fails and even CTRL-ALT-DEL fails to restart.

I've posted a new version of the -nvidia driver to our xorg-edgers PPA,
would you mind testing it either on Jaunty or Karmic and see if it
resolves this bug?

Get nvidia-graphics-drivers-180 - 185.18.14 here:

Using nvidia-graphics-drivers-180 - 185.18.14 under 9.04, the bug is still present.
The only way to get a usable desktop is to turn off all effects in Preferences/Appearance/Visual Effects (guessing this is compiz).

I will try upgrading to the latest development version of Ubuntu.

I updated my nvidia driver(s) as noted above and it seemed to work for a while ... then I discovered that if I left firefox running, it would lock up(!) - but only after the power management would idle the display - worked OK if screensaver running.
disabled display idle - no lockup
closed out of firefox - no lockup with idle display
Installed SeaMonkey yesterday - no lock ups since ... reenabled display idle
just a followup FYI

Bug is still present under Karmic. Turning off visual effects as noted above works around the issue.
I'm also not convinced that this is only a screensaver bug - I've seen the same rendering issues when working with an unlocked screen. Please reopen.

I'm noticing the same issue with 10.04 AMD_64. The symptoms match Jim's description in comment #11.

I'm running an integrated GeForce 7025 and Nvidia 9400GT. Three monitors - three separate xscreens. Let me know what information would be useful to collect here.
