Ubuntu :: Force Console Video Mode With Grub2 - No Monitor

Mar 25, 2010

I run a number of Ubuntu 9.10 boxes attached to multiple daisy-chained KVMs. None of the PCs are using any GUIs - they all run in console mode. I often reboot them remotely via an SSH session, etc. If a monitor isn't actually active on the PC when it reboots, Grub2 uses a low-res video mode, despite having a higher-res video mode set correctly in Grub2's configuration. If I reboot WHILE THE MONITOR is attached to the Ubuntu PC via the KVM, the video mode is set correctly as configured in Grub2's config files. If I reboot WITH NO MONITOR attached, the video mode is ignored and I'm stuck in a low-res mode next time I attach to the PC via the KVM. How can I force Grub2 to honor the configured graphics setting, despite not having a monitor present at the time it boots?

General :: Turn Off Monitor (Energy Saving) While In Text Console Mode

Nov 3, 2010

How to configure Linux text console to automatically turn of the monitor after some time? And by "text console" I mean that thing that you get on ctrl+alt+F[1-6], which is what you get whenever X11 is not running. And, no, I'm not using any framebuffer console (it's a plain, good and old 80x25 text-mode). Many years ago, I was using Slackware Linux, and it used to boot up in text-mode. Then you would manually run startx after the login. Anyway, the main login "screen" was the plain text-mode console, and I remember that the monitor used to turn off (energy saving mode, indicated by a blinking LED) after some time. Now I'm using Gentoo, and I have a similar setup.

The machine boots up in text-mode, and only rarely I need to run startx. I say this because this is mostly my personal Linux server, and there is no need to keep X11 running all the time. (which means: I don't want to use GDM/KDM or any other graphical login screen). But now, in this Gentoo text-mode console, the screen goes black after a while, but the monitor does not enter any energy-saving mode (the LED is always lit). Yes, I've waited long enough to verify this. Thus, my question is: how can I configure my current system to behave like the old one? In other words, how to make the text console trigger energy-saving mode of the monitor?

SUSE :: Nvidia Drivers And Dual Monitor Setup - Message Undefined Video Mode 31a

Jan 1, 2010

I have activated dual screen monitors using the Nvidia driver GUI as Sax2 would not correctly configure it. Now at every boot I get the message "undefined video mode 31a, press [enter] for a list of video modes or [space] to continue. After pressing space the system boots to my liking, how can I get rid of the message at every boot up?

I am using Suse 11.2 and KDE4.3.1 My video card is an Nvidia Geforce 7100 GS I thought I was using the Nvidia drivers as I have a GUI from Nvidia in my launch menu if I search "Nvidia" and I have completed the one-click installation. Although when I go into "My Computer" it says driver unknown.

Ubuntu :: Odd Resolution - Monitor After Switched It To TV Mode Then Back To PC Mode

Feb 8, 2011

When I first installed ubuntu 10.10, the display was for some reason tinted green and shifted a few inches to the right. After experimenting with the resolution preferences, I eventually got it to a large resolution (1280x720 ... or something like that) yet is was quite blurry. I found out that the problem was with my monitor after I switched it to TV mode, then back to PC mode. It became perfectly clear! All I had to do then was adjust the screen positioning by shifting it left a bit.

Even though I have made the resolution I figured out to be default, whenever I turn the PC on after shutting down, it goes back to the "green-and-to-the-side" mode. :/ Ain't really a big problem, until I tried to fiddle with the resolution preferences s'more.

Somehow, I have set it to be twice as wide of the maximum my monitor can display, went back to being green tinted for some reason, and is completely shifted left (yet the right side is still visible) This means that I cannot see what is going on the left side, and cannot adjust the resolution preferences, nor can I click blindly cuz the border is only around my visible side of the screen. Now it is stuck like this.

I've researched many hours and eventually found the terminal command for the resolution preferences. it popped up on the visible side. Although it was to no avail cuz I HAVE TRIED EVERY SETTING AND OPTION and absolutely nothing changed. I assume a system restore would simply revert it back to the previous satisfactory settings, but the thing is I want to FIX it. I am new to this terminal stuff, so I want to learn it and all that. To put it simply, here's what I want:

Learn how to manually adjust resolution without depending on a simple dialog box. Make the satisfactory resolution default and consistent through turning it on and off. Link that could teach me the essential commands, all this googling is stressful. D:

Ubuntu :: 11.04 Live CD: Force Classic Mode Even If Unity Will Work?

May 2, 2011

Is there any way when booting the LiveCD of Ubuntu 11.04 to force the use of classic mode, even if the computer meets the requirements to use Unity and would otherwise start Unity? Is there a kernel parameter that would do this? In searching, all I can find is the selection during login, but this seems to only show up after a full installation, I want to do this in the Live CD environment.

Ubuntu Multimedia :: Force Monitor Resolution At Startup?

May 4, 2011

I started using Ubuntu 11.04 today.
Everything works fine with my monitor directly connected to the computer. I get a default screen resoluton of 1600 x 1280, which is just fine.

However, when I connect the screen through a video splitter to be able to use a beamer, the screen resolution defaults to 1024x768. Moreover, Ubuntu then detects an unknown monitor.

I recall that I have solved this problem before with an older version of Ubuntu.
Now it seems that there is no xorg.conf anymore so I don't know what to do.

How can I force Ubuntu 11.04 to start with a screen resololution of 1600 x 1280.

Debian :: Force Single User Mode On Sun Ultra 5

Apr 26, 2010

I have successfully installed Debian on a Sparc Ultra5, 270MHz SparcIIi CPU, 384MB RAM, 40GB HD. However, once Debian tries to load Gnome (right before the login screen) the screen goes blank, and so the machine becomes unusable. I booted of the NetInstall CD, into rescue mode, and executed a shell, but apparently there is currently a problem when running nano from a live CD, so I can not edit the xorg.conf file when I boot the live CD. So, I would like to just boot the install into single user mode, but I dont know how. Currently, when the Ultra5 is powered on, it tries to boot with command "boot", so I hit "Stop A". From there I type "boot Disk1" to boot Debian normally. To boot from a CD, I would type "boot cdrom" So any idea on how I can boot from Disk1 in Single User Mode?

My only other idea is to hook up another monitor I have which may be able to deal with whatever resolution Gnome is defaulting to. However, Id rather just boot into single user mode.

Ubuntu :: Couldn't Use Grub2 Console Prompt To Log Back - Can't Get Anything To Work Correctly

Feb 1, 2011

Is this a beta version or something? I installed this version because it came as a live cd coupled with emc2 for cnc machining. I cannot get anything to work correctly. I tried to install Mozilla thunderbird using the application manager and it is very slow. It takes forever for the menus to open. or emails and is virtually unusable. I tried to use the startup manager and it killed my grub bootloader so I needed to reinstall. I couldnt successfully use the grub2 console prompt to log back into linux even though I ollwed several tutorials for this. I tried to install the flash player plugin and it kept telling me still to install it before I could watch flash videos even though I had installed it 3 or 4 times. I just tried to install evolution mail and it cannot log into my gmail account. I tried to install swift dove which is a faster version of thunderbird and it says it is starting but then never does. I am reasonably sure I should hang in there as I have heard Ubuntu is very good as an os.

CentOS 5 :: Rsync To A Samba Share Ignores Force Create Mode?

Jan 12, 2011

Have an issue with my CentOS server. I have a fully updated Centos 5.5 server and I have samba set up to serve shares to a couple of groups in my home office. I have it set up to force user/group and force directory create mode 770 and force file mode of 770. This set up works perfectly well for normal connections to the server; no matter who connects, all files and directories are owned by the specified users/group and create modes I specify. The problem is when I try to rsync some files to the same shares. When I do this, rsync ignores the directory/file forced create mode. It will honor the user/group, however. As an example, if I create a directory on one machine connected to the samba share, I get the following:

drwxr-x--- 3 nobody users 0 2010-12-26 20:42 Misc Pics

Debian Configuration :: Squeeze Grub2 Made Console Font Green

Apr 1, 2010

After an update on squeeze about a week or two ago, my console font turned green. I'm not exactly sure of the timing, because I switch between lenny and squeeze, and some time passed between the update and the reboot in squeeze.

During the update, I was asked if I wanted to keep my altered /etc/grub.d/00_header or take the package maintainer's version. I took the PM's version, knowing I'd lose my edit (set gfxpayload=1024x768x16). When I add that line to the new 00_header, run update-grub and reboot, the console font is the size I want, but it's a dull green. Reminds me of my first computer. How do I get it back to white and keep the 1024x768 resolution?

Currently booting with grub-legacy and chainloading grub2. If I boot entirely with grub-legacy, and pass vga=791, the console font will be white. It doesn't matter which kernel I use. Currently, I'm running 2.6.32-3-686. Same behavior exists if I use 2.6.30-2-686. If I use 1024x768x8 I get a dull gray instead of dull green.

Ubuntu :: Unable To Switch From GUI To Console Mode?

Mar 31, 2011

I'm having difficulty switching from GUI to console mode. I use ctrl-alt-f1 and the screen goes blank and I see a flashing cursor but I'm unable to do anything. I can switch back into GUI mode using ctrl-alt-f7. Also at times I see the word Ubuntu with 4 dots and 2 of them are orange if that's of any use. Like the initial boot loading screen.

I've tried going back to the default display drivers and that hasn't solved it. I'm using a CRT that's connected up to my display card via a VGA > DVI converter. *I've just checked and I can't get into recovery mode either
