What happened to Ctrl-Atl-Fx?

2Gnu · 07-07-2007, 06:25 PM

I can't get to a terminal using Ctrl-Alt-F1-7 since upgrading to 12.0 (which was a real PITA while troubleshooting my xorg.conf file).

Ctrl-Alt-Backspace & Del behave as expected.

I didn't see any similar threads. Is it something I did?

I noticed the same thing to.

I am having similar problems, only Ctrl+Alt+Fn actually appears to lock up X completely (Blank screen, Ctrl+Alt+Backspace does nothing, etc.) I ended up using the Alt+SysRq hooks to sync my filesystem and reboot. Luckily no lost work, but a troubling bug.

I wonder if the problem is with the OSS ati drivers? What cards are you using?

I had the same problem with Slackware 11.0. After instaliing Slackware 12.0 that problem vanished.
Have you configured your keyboards to something different from the US layout? I had played with different keyboard settings in 11.0 and people told me this is the possible reason if I have messed something up.

I've upgraded two of my three Slackware machines from 11.0 to 12.0, and I did not have that problem. One was a desktop, the other was a Thinkpad T43. Ctrl+Alt+F1-F6 worked fine for me at all times. Ctrl+Alt+Backspace worked fine as well when I had X configuration problems on one of my machines.

What motherboards do you have? Were all of you upgrading or were these clean installs?

thegoofeedude · 07-07-2007, 09:57 PM

I have noted that the problem only exists when X is running. My installation of Slackware 12 was a fresh install, and I installed the updated xf86-ati package from /extra. From a cold boot -- or after shutting down X by logging out of KDE -- I can use Ctrl+Alt+Fn to get to the other terminals just fine. However, with X running, doing a Ctrl+Alt+Fn leaves a blank screen. (I am pretty sure I am at the login prompt, but I cannot see anything.)

Is this concurrent with others who are experience this problem?

tramni1980 · 07-07-2007, 10:09 PM

With Slackware 11.0 I experienced exactly the same. I posted a lot in this forum about that. People suggested there was something wrong with the keyboard setting. Anyway, I never found the reason, because the problem was solved after installing 12.0 with the default US keyboard layout.
It would be nice if this problem be finally diagnosed

2Gnu · 07-07-2007, 10:17 PM

Default US keyboard layout here, same as always.

I did change the driver in xorg.conf from "keyboard" to "kbd" after the former caused X server errors.

thegoofeedude · 07-07-2007, 10:41 PM

I think it may have to do with switching video modes -- my desktop is dual monitor (dual head ati card) with xinerama where each screen is 1280x1024 whereas my default terminal is the VESA framebuffer 1024x768x256 (lilo passes vga=773 to the kernel at boot time.) After booting, I get the 1024x768 terminal cloned on both monitors, and Ctrl+Alt+Fn works fine. If I cause the bug to appear by switching to another virtual terminal while X is running, the keyboard still works fine, the screen is just blank. At this point, I am not able to get X to respond to Ctrl+Alt+Backspace.

kevkim55 · 07-07-2007, 11:01 PM

Not sure if this would help. Check to see if you have "DontVTSwitch" option enabled in you xorg.conf. Set it to false and see if the problem goes away.

Hmm. I'm running an Nvidia GeForce FX Go5200 64M with the NVIDIA-Linux-x86-100.14.09 driver - same as with 11.0.

Here's my xorg.conf file:

Perhaps you could try using the open-source driver, nv, in your xorg.conf and see if you have the same problem.

kevkim55 · 07-07-2007, 11:54 PM

My guess is that this has to with the wrong/incorrect keyboard layout. Try using pc105 or pc104 layouts and see if this helps. Also, try enabling xkb extension. This is how I got it to work on my BLFS system. You might have to install xkb package if you don't already have it.

Tried modifying the keyboard section as follows, no change:

Code:

Section "InputDevice"

    Identifier     "Keyboard0"
    Driver         "kbd"
    Option     "XkbRules"      "xorg"
    Option     "XkbModel"      "pc105"
    Option     "XkbLayout"     "us"
    Option     "XkbVariant"    ""
    Option     "XkbOptions"    ""

EndSection

Just to say, I can use Ctrl+Alt+F6 to get to a terminal in 12.0. This didn't work for me in 11.0!
