I've just upgraded to a new monitor, that has a default resolution of 1920x1024. How do I set Grub2 and consoles to use 1920x1024? Right now I can't use any console (Ctrl-Alt-F2). I'm using Ubuntu 10:04 x86_64.
View 5 RepliesI 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)
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):
Code:
02: None 00.0: 11001 VESA Framebuffer
[Created at bios.464]
Unique ID: rdCR.7IS+B23HFDE
Hardware Class: framebuffer
[code]....
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
View 2 Replies View RelatedI have got myself into a situation where I see nothing during boot until X starts, and I have no text virtual consoles. I recently replaced my old 9.10 system running on hardware that seemed to be breaking down, with a new system with both an onboard graphics chip (which I disabled in the BIOS as the 1st step), and an Nvidia GeForce 8400 GS card. I installed Windows XP then Ubuntu 9.10, copied all my files across, modified /etc/fstab, /etc/hosts, etc etc., and as the last step I unplugged the 1920x1440 IBM CRT that I'd used during the install and tweaking, and plugged the display into the BenQ LCD on a Belkin 4-port KVM. Oh, I also installed Windows and Splashtop (that mini-Linux that fast boots from the Windows NTFS partition).
I had a problem at that point: I had a lot of trouble getting any signal on the LCD monitor, and eventually got it working but with the whole display half-shifted off the screen (everything was shifted to the right about six inches), and the Ubuntu splash during boot (the sort of spotlight effect with the glowing horizontal line with the light animating along it left and right) was shrunk and only occupied part of the screen. Nor could X detect what kind of monitor it was. I had a lot of problem with a lot of attempts prodding the LCD monitor to complain "Out of range!" (over the top of the Ubuntu three linked circles). I couldn't fix the problem, and in the end installed the Nvidia proprietary driver and ran its X configurator, and suddenly everything snapped back and began working correctly: X ran happily in 1680x1050, filling the screen properly, and X could now correctly detect the monitor as a BenQ.....
I have a big issue that i can understand (and i didn't find any answers) When i boot, i only have the fullscreen console (tty1 to tty6), which ask me to login.If a try a gedit it says that there is no display. Startx doesn't work neither.
Before this, i tried to update from 10.04 to 10.10, but I had some issues with the update manager. On looked on google for solutions and I tried a couple of those: I updated my source list with maverick ppa, I removed the nvida driver
I'm building a web kiosk and I'm trying to figure out how to disable the ability to switch to tty2-6. All the references I've found refer to a process on older versions of Fedora.
View 11 Replies View RelatedI 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:"
CONFIG_VT=y
CONFIG_FB=y
CONFIG_FB_VIRTUAL=y
CONFIG_DUMMY_CONSOLE=n
CONFIG_FRAMEBUFFER_CONSOLE=y
CONFIG_VGA_CONSOLE=n
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:

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
Code:
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.
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.
How large would a program have to be to open two text consoles on the same physycal console? And what would the general outline be?
View 9 Replies View RelatedI 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).

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 googled on how to disable the extra virtual consoles... I don't need 6 of them and decide to cut it down to 3 There was no luck with Google so I did this my own and seemed to have done the job...

I just upgraded to openSuSE 11.4 from 11.1. In 11.1 the contents of the virtual consoles are kept after a logout, so if I login again, I get the same environment as before. In 11.4 the contents are lost. How can I switch on this feature again?

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.

View 2 Replies View RelatedI 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?
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?
How can I tell screen to always show created virtual console names in the bottom. I am using Ubuntu.

I installed Fedora 15, which was my first real departure from Debian based Linux OSs. I absolutely love the new Gnome 3, and was able to configure F15 to work as I wanted it to. On rebooting I realized that there was no boot loader screen, that F15 just booted and didn't give me a choice as to which OS I wanted to use. Eventually I was able to configure grub to let me see the boot loader and added my old boot loader as a choice. This worked well, maybe not a perfect solution, but it worked. This weekend I installed LMDE (Linux Mint Debian Edition) to another HDD. LMDE uses grub2 and after the install F15 was not recognized.
Two questions: Is there a way for grub2 to see F15? or Can F15 be installed using grub2? I really don't mind re-installing from scratch.
Is there any Linux software that allows accessing a pre-configured serial console via Browser using a java applet? I would like to access the serial management consoles of various hardware devices via browser.

View 2 Replies View RelatedI tried searching for this both in the forums and on google but it seems that everything goes back to MBR installation. I know that "grub-install /dev/sda1" should install it to the sda1 partition, but instead of installing it keeps giving me the following error:

I tried this with a fresh installation of Karmic on both of my PCs. I tried with --recheck option as well, same error.

Every single guide I found installs GRUB2 to MBR, and some briefly reference to "grub-install /dev/sdaX" without going into any detail. At first I thought the problem was because Ubuntu was installed on a logical partition, so I created a separate /boot partition and formatted it as ext2, still getting the same problem.
