General :: Virtual Consoles Are Not Coming Up?

Apr 26, 2010

I recently installed RHEL 5.2 on my system. I found that I was not able to show up virtual consoles that we generally do by hitting Ctrl + Alt + F1 through F6.

I installed Red Hat again but the same problem is there. However, I can go into Run Level 3 by

init 3

but it takes too long to display the prompt. Besides, hitting Ctrl key generates error "unrecognized key" something like that.

Today I installed Virutal Box on Windows XP Host. Then I installed RHEL 5.2. There also I faced the same problem.

However, Virtual Box works fine and I am glad that I can now have only one Host OS on my system and then install as many Guest OSes as I want. Dual Boot System was giving me a heacdache.

OpenSUSE :: Keep Contents Of The Virtual Consoles After Logout?

Fedora :: Missing Virtual Consoles After Upgrading Packages?

Apr 4, 2010

I installed 64-bit Fedora 12, and everything was working fine. I upgraded a bunch of packages (including, but not limited to, X and Gnome) via yum, and now I'm unable to access virtual consoles. X works fine, but Ctrl-Alt-F2, etc. leads me to a black screen.

How do I get my virtual consoles back?

Debian Installation :: Virtual Consoles Are No Longer 25x80 On Squeeze?

Jun 12, 2011

On Debian lenny, when I wanted to go from X to a virtual console, I would type (for example) <Ctrl> <Alt> <F1>. Then I got the traditional 25x80 screen, which is wonderful in bad lighting conditions.

On Debian squeeze, virtual consoles are no longer 25x80. They fit way more than 25x80 characters on the screen. They go through the frame buffer, which I guess I must keep that way because otherwise it would ruin X.

But I want my 25x80 back, for those bad lighting conditions.

If I set /etc/default/console-setup to FONTFACE="VGA", at least I get a readable font.

ANd if I set /etc/default/console-setup to SCREEN_WIDTH=80 and SCREEN_HEIGHT=25, they do the obvious, but the characters are just as small, and the data is all in the upper left corner of the screen.

How do I get 25x80 so it fills the screen, as in the days of lenny, without removing /dev/fb0?

General :: Ubuntu - Using Multiple Consoles + Vim

Jul 12, 2010

I am gradually getting used to the CLI for Ubuntu. I am used to switching between windows when editing a file, going to the command line to run a cmd, and then back again etc.

I feel severly restricted by the CLI, as it seems I can only do one thing at a time. Surely, there must be a way where I can 'switch between' several command line consoles?

Also, I am using vim, and I sometimes need access the command line. At the moment, I have to quit vim to get to the CLI, and then start vim again. This is not very productive.

How to switch between CLI screens/consoles and also how to switch to the CLI from withinin vim and then back to vim again without having to close vim?

My distro is Ubuntu Lucid Lynx (10.04 LTS)

General :: Multiple Consoles - Used VFB As Temp?

Jan 11, 2011

I am attempting to setup linux in my embedded environment. I wanted to output the console display though the tty serial port and the vt. Since I don't have a frambuffer hw driver yet, I just wanted to use the vfb as a temp.

So, this is what I did in my configuration file:
CONFIG_CMDLINE="console=ttyS0,115200n8 console=tty0 mem=126M video=vfb:"

I would expect the tty output to go to the uart as well as the virtual-console; this does not seem to be the case, as no vt functions are called when I execute prompt commads - I can see the console in my serial terminal, and this all works fine.

Here are extracts from my boot:
Kernel command line: console=ttyS0,115200n8 console=tty0 mem=126M video=vfb:
Console: colour dummy device 80x30
console [tty0] enabled
Console: switching to colour frame buffer device 80x25
fb0: Virtual frame buffer device, using 1024K of video memory
Serial: 8250/16550 driver, 4 ports, IRQ sharing disabled
serial8250.0: ttyS0 at MMIO 0x3e000000 (irq = 99) is a 16550A
console [ttyS0] enabled
serial8250.0: ttyS1 at MMIO 0x3e001000 (irq = 9 is a 16550A
serial8250.0: ttyS2 at MMIO 0x3e002000 (irq = 97) is a 16550A

Here are my console binding results:
/ #
cat /sys/class/vtconsole/vtcon0/bind
/ # cat /sys/class/vtconsole/vtcon0/name
(S) dummy device
/ # cat /sys/class/vtconsole/vtcon1/bind
/ # cat /sys/class/vtconsole/vtcon1/name
(M) frame buffer device

General :: Ubuntu - Command-line Program That Switches Consoles?

Jun 18, 2011

For whatever reason, the "Ctrl-Alt-Fn" sequence has no effect on one of my Ubuntu machines; the sequence is interpreted as ordinary input. I need to get the system to a console because I'm trying to do a dist-upgrade and that's going to bounce gdm etc.

Is there some command-line tool that can be used to switch consoles? I have some vague distant memory of that being possible.

(I'm running Ubunty Jaunty at the moment. Yes I know it's old; I'm trying to march forward.)

Ubuntu :: Tty Consoles Don't Show Up (notebook)

Aug 4, 2010

The problem is: CTRL-ALT-F1 etc does not give me the login consoles and i strongly suspect it has something to do with the notebook display adapter (a problem on its own, but in this case it seems to be the INTEL GMA).After pressing the key combo, the HD is working on something, but all I get is a frozen picture of my current (tty7) Desktop. After hitting CTRL+ALT-F7 it blacks out for a moment, comes back to normal gnome Desktop as if nothing happened.I tried setting different vga modes in grub (according to my research, this also sets tty consoles modes ?) with no luck.The output of 'hwinfo --framebuffer' is as follows (if it's of any help):


02: None 00.0: 11001 VESA Framebuffer
[Created at bios.464]
Unique ID: rdCR.7IS+B23HFDE

Software :: Out Of Frequency During Boot And On Consoles?

Aug 3, 2011

On the weekend I installed and played Crayon Physics Deluxe, and when I closed it it caused some graphics problems. I thought nothing of it and shut down the system. When I next booted the computer it gave a warning about hard disk erros at first, then rebooted, and then just gave me an out of frequency error right after the BIOS splash screen.

As I did not know what to do and where to look for the root of the problem I eventually set up the system (Ubuntu 11.04) anew, and even completely formatted the partitions for / and /home, so that absolutely everything should have been as it was on day one. But since then, even though the partition for / had actually been deleted and then created anew, instead of the Ubuntu splash screen I continue to get this out of frequency error until the login manager appears. And what's much worse, I get it immediately as soon as I switch to any console with Ctrl + Alt + F2 or any other, so I cannot use any console.

Then yesterday Skype had a crash, and again the whole thing started, after rebooting I only got the out of frequency error, nothing else. So I set the system up again, but the situation is still the same, the out of frequency error up to the login screen remains, and it also remains on the consoles.

There is no problem whatsoever with any system booted from CD. As all actual data had been wiped during the reinstall, I suppose that the problem must be connected with grub 2, some misconfiguration in the boot loader - but I have no idea how to check or change what's there.

The graphics adapter is a GeForce 7025 with nvidia driver 270.41.06. The Ubuntu setup offers two drivers, this is the older one apparently, but it's the same thing with the newer one. The monitor is a PKB Viseo 230Ws at 1920x1080 pixels, H 67 kHz and V 60 Hz.

Slackware :: Consoles Don't Display Any Output

Feb 6, 2011

I am using a 64-bit Slackware 13.1 distro (I chose 64 by mistake, to be honest, as I know there's less trouble with a 32-bit distro) and I have some problems with my consoles (in text mode). After changing the runlevel in ininittab to graphic mode (4), I can't enter any of my consoles. Actually, only ctrl+alt F1 shows some output, regarding the graphic mode (I'm currently using KDE4, the default for slackware 13.1) and F6 is the only normal consoles I have access to. However, if I log out and log in (with another user, maybe) there's no output anywhere (not on F1, neither on F6).

General :: Permissions - Would Map The Owner Id Of Files Coming From Other Computers To The Account Name In /etc/passwd?

Feb 8, 2010

When I use ls -al to show files downloaded from internet,

-rw-rw-r-- 1 427 6011 7544 Jul 20 2006 INSTALL
-rw-rw-r-- 1 427 6011 4229 Dec 9 15:36
-rw-rw-r-- 1 427 6011 27893 Dec 10 17:47

I can see the owner and group ids are shown because there are no corresponding entries in /etc/passwd and /etc/group respectively. I don't know much about linux and dare not to edit these files, I wonder if somebody already knows whether linux would map the owner id of files coming from other computers to the account name in /etc/passwd and display them when necessary (for example, when using ls -al)?

OpenSUSE Install :: The Alternate Consoles Not Working?

I am neither sure what these are called not if this is the proper place to report the problem, please let me know if there is a better place.The consoles that should ne invoked using CTRL-ATL-F1...Fx are simply not there or cause my OpenSUSE 11.2 64-bit to crash. If I hit a combination like CTRL-ALT-F3 (say), my screen goes completely black (there is absolutely nothing on screen), not only that I cannot return to X (using Gnome, if that makes a difference), none of the CTRL-ALT-Fx work after that and I must do a hardware reset.

Ubuntu :: Way To Force Consoles To Be In Lower Resolution

Oct 1, 2010

I upgraded from 9.04 to 10.04.1 so I am still using legacy grub.Anyway, I noticed with the update that the console is using the framebuffer and using VESA for high resolutions.I really don't like or want this feature. So I added vga=0 to get 80x25 and it works initially but just when the X server is running (Xubuntu in my case) I can see how the console switches to a high resolution again. After this, if I go to a console, lets say tty1, it is using again a high resolution instead of 80x25 (VGA). Is there a way to force the consoles to be in a lower resolution and keep it that way? It used to work fine in ubuntu 8.xx and 9.xx
