From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.8) Gecko/20050524 Fedora/1.0.4-4 Firefox/1.0.4 Description of problem: This problem occurs both on a macine updated from FC4 test 3, and also on a laptop upgraded from FC3. (Both machines are now on the official FC4). Xscreensaver does not show any previews in xscreensaver-demo, and although it will blank the screen that's all it will do. Here's the output from xscreensaver: [sleepylight@localhost ~]$ ps -A | grep xscreensaver 2816 ? 00:00:00 xscreensaver [sleepylight@localhost ~]$ kill 2816 [sleepylight@localhost ~]$ xscreensaver xscreensaver: 08:27:54: no keyboard or mouse data in /proc/interrupts? xscreensaver: 08:30:50: blanked A: brk grew by 36K. /bin/sh: /xscreensaver/grav: No such file or directory /bin/sh: line 0: exec: /xscreensaver/grav: cannot execute: No such file or directory xscreensaver: 08:30:50: 0: child pid 3523 (${libexecdir}/xscreensaver/grav) exited abnormally (code 126). And here's the output from xscreensaver-demo [sleepylight@localhost ~]$ xscreensaver-demo xscreensaver-demo: 08:27:24: Gtk-critical: gtk_list_store_get_path: assertion `iter->stamp == GTK_LIST_STORE (tree_model)->stamp' failed I haven't done anything to change the screensaver setup, so I'm really at a loss to figure out what went wrong. Version-Release number of selected component (if applicable): xscreensaver-base-4.21-4 How reproducible: Always Steps to Reproduce: 1.allow xscreensaver to start. 2. 3. Additional info:
In FC4 only the blank screensaver is provided by default. If you want more screensavers you need to install the xscreensaver-extras and/or xscreensaver-gl-extras packages. Upgrading from test3 isn't really supported. If you can't do a fresh install of FC4 then you'll need to manually remove your ~/.xscreensaver file after installing xscreensaver-extras and/or xscreensaver-gl-extras. (this step shouldn't be necessary for your upgraded FC3 install)
