ctrl-c kills xserver

[Alex Wauck]

Binary package hint: xserver-xorg-core

I am running the first Jaunty alpha (up-to-date as of Mon Dec 1 18:00:50 CST 2008), and pressing ctrl-c kills the X server. Also, pressing alt-<f-key> or alt-<arrowkey> causes a momentary vt switch. It would appear that the bug with X allowing keystrokes to propagate to the underlying vt is back.

Am I the only Jaunty user who is encountering this? I would really like to be able to copy, paste, and switch desktops at will with the keyboard.

Hi awauck,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

I can reproduce the same issues. Alt+Fn and Alt+Cursor consistently don't work, I reported that yesterday as bug 305641.

I can also perfectly reproduce the Control-C problem, however, that doesn't work in all applications. It reliably kills the server in gdm, and I also often get it in a Terminal. E. g. one of my muscle memory things is Control-R, search history, press Control-C when I didn't hit a result.

Oh, I don't have an xorg.conf.

I don't believe that this is hw specific, but attaching lspci anyway.

My understanding is that this bug is caused by libdrm-intel1, which comes from an upstream git snapshot. Presumably, this problem is a known issue and will be fixed by upstream.
However, if this happens to anyone with a non-Intel graphics chipset, make a note of that in this bug.

I've been reading up on this since I kept hitting ctrl-c and killing X on my laptop for the last week or so. From what I've been able to gather, this only happens if you do not have an xorg.conf. I worked around this bug by creating an xorg.conf with only the following:

Section "ServerFlags"
         Option "AllowEmptyInput" "true"
EndSection

Now X doesn't die when I hit ctrl-c, alt-Function keys work as expected.

Thank you so much! I confirmed that this fixes it. This bug caused me
a lot of biting into the table and quite some data loss, so I'm glad
that it's back to sanity now with this workaround.

I confirm that the current 1.6beta3 server in jaunty has this fixed.
