Description of problem: After login, X can crash when the ENTER key is pressed Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.10.2-1.fc15.x86_64 How reproducible: May do it many logins in a row then start working again Steps to Reproduce: 1. Press ENTER soon after logging in, doesn't seem to matter which application it is in. 2. 3. Actual results: X crashes; submitter wails "Not again!!!!" Expected results: No crash, happy submitter.

Note that I am able to log in ok - which requires pressing ENTER.

If it helps or not, I am having the same exact issue: Backtrace: [ 873.948] 0: /usr/bin/X (xorg_backtrace+0x2f) [0x45e7ff] [ 873.948] 1: /usr/bin/X (0x400000+0x62e86) [0x462e86] [ 873.948] 2: /lib64/libpthread.so.0 (0x3663400000+0xeef0) [0x366340eef0] [ 873.948] 3: /lib64/libc.so.6 (__select+0x13) [0x3662cd91d3] [ 873.948] 4: /usr/bin/X (WaitForSomething+0x186) [0x45c276] [ 873.948] 5: /usr/bin/X (0x400000+0x2eb4a) [0x42eb4a] [ 873.948] 6: /usr/bin/X (0x400000+0x22e1a) [0x422e1a] [ 873.948] 7: /lib64/libc.so.6 (__libc_start_main+0xed) [0x3662c2139d] [ 873.948] 8: /usr/bin/X (0x400000+0x23101) [0x423101] [ 873.948] Fatal server error: [ 873.948] Caught signal 3 (Quit). Server aborting [ 873.948] [ 873.948] For me, some arbitrary amount of "Enters" are fine, but then one, regardless of application kills the X server. I have been using the current installation since the 14th and used the latest packages. It just started today (the 19th).
I don't think that this is an X problem anymore. In my case I think that it is a kdm problem. The only time that I get this is when X starts on vt2 (ps -fe | grep X will show where it is). If I kill X, it will restart on vt7 as expected and I don't get the problem. I have to do this every time I boot. If I don't, I get a less than subtle reminder at some point...

I don't think it's restricted to kdm, because I'm using gdm (and XFCE). > If I kill X, it will restart on vt7 as expected > and I don't get the problem. > > I have to do this every time I boot.

As mentioned in Bug 766520, a newer kernel (2.6.41.9-1 on F15) seems to fix this problem.
This bug is still present for me on 2.6.41.10-3.fc15.x86_64 (F15)
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
