Virtual Consoles

When I got RH 7.0 working, the ctl-alt-F2, etc. worked fine for a while. Then it quit working! Now if I am in Gnome or KDE and try ctl-alt-F2 I get a blank (black) screen, and ctl-alt-F7 will not bring back the GUI. In fact, I am at that point locked up so that a power off and power back on is the only way to resurrect the system.

Can anyone help me?

Re: Virtual Consoles

Hello Dale,

It seems that you have some kind of videocard misconfiguration. I've seen cases where X disrupts the text consoles when you switch the VCs using Ctrl-Alt-Fn. You should try to re-configure your Xserver to use default vga (It will be horrible, but it's just for testing purposes) and see if the problem still happens. If it does, it's a matter of fine-tuning your Xserver config.

Re: Virtual Consoles

Paga - Thanks! I am slow, but please don't give up on me. I am a newbie with Linux, and do not always know *how* to do something. Your reply makes sense, because the V.C. failure occured about the time I "fixed" the resolution on my monitor. I'm not sure how to go back to just "VGA" but I will try. Editing XF86Config-4 did not help, because the file is too complicated for me to know what to do. Should I try linuxconf or Xconfigurator?

Thanks again - Dale

Re: Virtual Consoles

Hello again, Paga
I tried Linuxconf and got a lockup. When I rebooted, there were boot errors regarding the Screen, and all I got was a text console. So I ran Xconfigurator to reset the Display to 800x600 (best choice for my monitor). It then booted back to my GUI, but ctl-alt-Fx still gave me a black screen and a lockup. You suggested a test in which I re-configure my Xserver to use default vga. I just don't know how to do that. Can you help me find documentation on how to do this?

Thanks - Dale

Re: Virtual Consoles

Hi,

Do you know the chipset of your video card?

Anyway, you can try to change to a vc on which you're already logged in and then type 'reset' to reset the console. This might just work..

Re: Virtual Consoles

Hi, Vincent!

I cannot *get* a console on which to type "reset". I tried it in a Gnome Terminal, but nothing happened.

My XF86Config-4 file contains the line:

device:
"Intel Corporation|82810 CGC [Chipset Gra"

Does this help?

I really need a console, I believe, because there are times when one would like to just enter commands. Right?

Thank you. Any further help would be greatly appreciated!

Re: Virtual Consoles

Hi Dale,

So you mean that you don't even get a prompt when you open a gnome term?

Anyway, I suspect problems with your X configuration. Could you please post (or attach) the following:

- output of "lspci -vv"
- your XF86Config
- /var/adm/XFree86.0.log

Regards,

Vincent

Re: Virtual Consoles

Hi, Vincent!
I am able to get a Gnome terminal. The reason I am seeking Virtual Console functionality is so I can learn more.

Per your suggestion, I tried the command lspci -vv, and got a 'no such command' message.

I have attached (I hope) the other two things you wanted.

Thank you - Dale

Re: Virtual Consoles

You have to be logged in as root to execute lspci.

Another thing to check is at the LILO: prompt, type 'linux single' and see if it brings you up to a shell prompt.

Your XF86Config-4 settings should have no effect on the virtual console. They are always standard VGA, unless you are running special vga modes out of the lilo.conf or using a package like SVGATextMode.

Including the output of dmesg would be helpful too, to see if there are any failure messages from the kernel at boot time.

Is this a hand compiled kernel, or an out of the box kernel, and what distrobution if so?
