Ubuntu Servers :: How To Lower Shell Resolution
Feb 18, 2010
I needed Ubuntu server and recklessly picked Karmic. Hardware is some regular 775 mobo with integrated Intel graphics. Monitor is ASUS VH222D. Installation went smoothly but after that problems occurred. Shell is displayed in 1920x1080 resolution and fonts are so small almost unreadable. Grub2 looks OK, standard non-fb and so does few rows of text after loading grub but soon after that framebuffer becomes active.
dpkg-reconfigure console-setup doesn't mention resolution. Some articles are leading to grub2 gfxmode but none of manuals helped. I just cannot change grub2 menu resolution to anything else than standard console fonts (non-fb). Kernel option vga=XXX is no longer working.How to lower shell resolution? Why is this automatic???

How to lower the resolution of all the images in a pdf? I searched around and couldn't find an answer to this. I have a pdf file of a textbook that I use in school but each page is an image of 2 pages of the textbook (left page, right page when the book is opened) and each image is of a very high resolution. I downloaded pdftk and pdfedit but for such a simple problem, I'm having trouble. Is there any way to do this?
I have tried converting the 380 MB PDF file to PostScript but after an hour of doing that, it stopped, and the PostScript only had about 17 pages instead of the 733. So converting it back to a PDF file to utilize pdftk's algorithms would have been worthless. I know I could split up the pdf file into sections but I'd rather just scale down all the images, or make them mid quality PNGs or high quality JPGs just so the filesize can be halved.

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

One day when i logged in, my screen resolution became lower. The sistem do not recognize anymore my old resolution (native) 1600x900 . And you can realize that maybe there are problems with the video card, because the system is slower than before in this terms. What could have happened?

This is some thing that I've noticed with any install of Ubuntu whether its regular Ubuntu or Kubuntu etc. The splash that comes up with the distro name Ubuntu/Kubuntu on start up look perfectly fine and as it should until I've installed my Nvidia drivers. then it goes all bung.
Lower Resolution. Slightly different colouring and Not taking up the whole screen. Sometimes it even sits slightly to the right.
Is there a way that I can fix this? I know its nothing all that major but it would be nice if it looked as its meant to.

I've recently got a HDTV LCD display (BenQ SD3742), and a nettop (Acer revo 3610) to go with it. I connected them using an HDMI cable, and I installed the latest Ubuntu 10.04 64 bits edition.I then installed the latest nvidia drivers (nvidia-current package, which is nvidia-glx-195) to support nVidia ION platform using this ppa: https://launchpad.net/~nvidia-vdpau/+archive/ppaAccording to various websites, my LCD is FullHD, so I should be able to select 1920x1080 resolution. But the automatically selected resolution is 1280x768, and in nVidia configuration panel, this resolution is stated as being "native resolution" for my screen (its name is correctly detected by Ubuntu, by the way!).If I select 1920x1080 and "Apply", the resolution is changed but the borders of my desktop are not available... and the image looks deformed anyway.Is there any way to make Ubuntu to detect properly this LCD display in its real native resolution (FullHD, 1920x1080)?

I'm trying to dump a mysql database on a small web server without killing performance. I tried using the nice command to give the mysqldump and gzip a low priority, but gzip is still taking up 100% CPU. Pages on the web server are loading incredibly slow. Here's my command:
Code:
nice -n 19 mysqldump -u USER -pPASSWORD DATABASE | nice -n 19 gzip -9 > OUTFILE.sql.gz How do I get gzip to run without taking up 100% CPU? I've attached a screenshot of top about 8 seconds into the dump.

Canceled a sys backup in progress now my Waste bin is at max and must be emptied.However OpenSuse 11.3 contradicts itself by claiming there is 0 in the waste bin? Perhaps there is a Bash command that would solve the problem

Is there a way to determine the native resolution of the current console display device from the shell?
I know I can get the current console settings, but I'm looking for the native screen size of the display hardware, whether or not it conflicts with settings.

Installed server 10.04 using an old Sony 19" multi scan 400ps CRT monitor. The command line font is less than 1/8" high: something on the order of a large 4pt or small 5pt font. Made several attempts to locate the correct info using the man functions and searching the archives, but so far have not been unable to find the needed information. The eye strain is about to make me eligible for a white cane with a red tip.

am just coming from a clean install of Lucid Server x64 on a desktop configuration. No problems really but for one.With no GUI installed -something I wish to remain as is- I am having difficulties browsing through bash due to low resolution. So the question is: "how can I go to a higher screen resolution?"

I've installed and reinstalled Ubuntu server 11.04 about five times now.
I want to have the LVM, with an encrypted partition for holding / and /home (the swap is not encrypted).
Each time, after installing the resolution (I have not installed GNOME) is very bad and the prompt for entering the key to unlock the disk seems to scroll each time a character is entered.
The system is almost unusable at this resolution.
What can I do? I want to have an encrypted disk, but it seems at the moment that the only way to have a workable system is to install on an unencrypted partition.

I've just installed Ubunter Server 9.04 (after having installed 9.10, having problems with it, and uninstalling it). Mostly, 9.04 is working well so far, but for one nuisance: the font is huge.
Well, okay, not huge, but big. On my other machine, running Ubuntu 9.04 desktop, same size monitor, I have the resolution set to 1440x900 which gives me 46 lines on the CLI (with the window maximized, but not full-screen). On the server machine, however, I'm getting only 25 lines -- and there's not even a window title-bar, menu bar, or panels taking up any of the landscape.
So my question is this: Not having a GUI nor any of the associated display-management software, how can I set the screen resolution or otherwise get my display font smaller, using the CLI?

I've just finished installing Ubuntu Server 10.4 onto my ASRock ION330. I don't have a spare monitor lying around, so I've plugged my TV into my machince via HDMI. This works, but the text is tiny. There are too many rows and columns of characters (or equivalently, the font is too small). When I try changing the TV resolution to a smaller size, it just cuts out the rest of the text. So from the command line, how do I make the text bigger?

Would someone please point me in the direction of how to change the display resolution on Ubuntu server version 9? I am talking about the actual VGA port on the back of the server. I am NOT talking about anything related to XWindows or a SSH session. This is a text based display. When I installed Ubuntu Server 9 on my server I picked a larger display resolution than I really want.

Trying to connect an intel atom based TC which uses the Intel D945GSEJT motherboard. We have several old AcerPower F1 PCs which connect OK but the new TC doesn't provides a weird screen resolution at the LDM - 1152x864. I've logged in and looked at the monitors section and it thinks there is a laptop monitor for some reason in addition to an undetected monitor. If I try to change anything I lose my mouse which is VERY strange.
If I boot 10.04 using a USB memory stick on the TC everything is fine - I can get 1280x1024, the monitor is detected and all is well. I've tried changing monitors, fiddling with lts.conf etc with no success. For info, my current lts.conf is as follows
[default]
X_NUMLOCK = True
X_COLOR_DEPTH = 24
LDM_DIRECTX = True
[Code]...

I have a question about using bourne for a shell script. I have a script that at the moment performs a logical dump of my database, backups up the physical files of the database, and backs up everything within /var/www
I want to be able to copy the files over ssh to a remote server. However, the only way I am able to find examples of doing this is when you exchange keys and do not need to provide a password. How can you write a script that requires a password, not key exchange? I was told I specifically have to do it this way.

The short version: I have to manage some virtual machines using php shell_exec function, so far I cant do this because apache is run by the user www-data and virtualbox by the user vboxuserFrom what I've read so far, I've thought of 3 possible solutions: 1.- Create a script on my vboxuser that I can call from php to manage the Virtual Machines.2.- Change the apache user from www-data to vboxuser so I can manage the Virtual Machines through php
3.- Reinstall VirtualBox, this time using www-data as my user. I'm not sure if any of these will work and I'm not too sure of which would be the best solutionNow the longer more detailed version:
I have a remote server running Ubuntu 10.04.2, in that server I have set up VirtualBox so I can run several instances of WinXP to perform different tasks. Everything is setup and I can manage the virtual machines through SSH. If I want to run them as a different user than the one that created them (a user that so far only has been used to create the Virtual Machines) I have to do sudo -u vboxuser.Now, I need to create a PHP script to manage these virtual machines (I know about phpVirtualBox, but it's not what I need). If I try to run the virtual machines using shell_exec() from php, I get no answer at all (And I have tested that shell_exec is working on my server).

I have just installed Ubuntu Server 10.04. With Version 8.04 I had no problem to change the resolution from 640x480 to 1440x900 (console, no GUI installed). With 10.04, it does not work, the only resolution that works is 640x480. I have tried the following:
Changed: GRUB_GFXMODE=1440x900
Result: Success, Grub comes up with 1440x900, but when booting, the resolution changes to 640x480
Changed: GRUB_GFXPAYLOAD_LINUX=1440x900
Result: Booting -> blank screen > automatic reboot
Changed: GRUB_GFXPAYLOAD_LINUX=keep

whether I should encounter a problem relating to output redirection when using sed from a shell script which is ran by apache? I have given apache privileges in sudoers to run the shell script and the commands within it. However the problem is that when I check auth.log all commands are listed except the sed ones, yet if I run the shell script directly from the command line they work fine and are logged.
So although I realise I probably have some permission issues to solve, I think its strange how sed commands are not being logged at all. would also appreciate any advice on apache and sudoers, am I playing with fire here? Im on lucid 10.04 server

When I add a new user and SSH to my server as that new user, my command prompt is just a '$'. Tab completion doesn't work either. What I notice is that I get this:
Could not chdir to home directory /home/scaldwell: No such file or directory
$
Echo PS1 yields nothing. There is also nothing in /etc/skel. I didn't have to do anything special to get my initial user setup with the right prompt, and the second user has been added to the admin group as well. I have noticed that if I issue the command sudo chsh -s /bin/bash the account gets the correct prompt.

I am running Ubuntu Server 10.04 and I just created a new user. Everything works great except the new user's SSH shell can not do certain things.
For example, I cannot arrow up for previous commands on the new user. I just get "^[[A" when I try that. (I can do this on root.)
It also looks different on root versus the user, look:
