General :: Virtualized Screen Resolution - Use A Larger Size Display That Is Configured By Default
Apr 18, 2010
I have a 64 bit Ubuntu 9.10 workstation with two virtualized guest OSes using KVM/QEMU. Also both 64-bit. One is Fedora 12 the other is beta of Ubuntu 10.04.
The problem is that I would like to use a larger size display that is configured by default.
Both guest OSes have a maximum screen resolution of 1024x768. I would like to increase this to something like 1280x900 or 1440x900. The resolution of the host system is 1920x1080.
This configuration appears to be a result of the installation detecting the resolution being reported by the virtual screen during installation.
The only information I have found on the subject suggests modifying the xorg.conf file in the /etc/X11 directory. Neither guest system has this file.
I tried creating one by hand in the Fedora system and managed to render it completely unusable. Not a big deal as this is recently installed and can be reinstalled easily.

In Ubuntu 11.04, all windows display larger than the available screen size, and I haven't found a way to make them fit within the display area of the monitor. This is a Dell 19" flat screen monitor, and I've tried changing the display; no matter what resolution is selected, the windows all bleed past the screen.

So I know now that I reach the login screen, and I know to hit control, alt, f1. However, all attempts to reset the resolution have failed. Here's how it went down. I was working with nvidia driver. Already was frustrated I couldn't get a working wide screen setting for my toshiba hd tv/monitor but that's a seperate issue. I was trying to get the driver to recognize my separate monitor to an hd tv in the living room using the video out. works fine with windows. I got it to recognize, it made me save settings, and then restart. Note resolution settings are set to automatic right now. Then when I restart, I get to ubuntu splash screen, it plays the chime, and shows a blank black screen. Control alt f1 brings me the menu.
I have been told to type (this is just quick type, I used the proper commands in reality)
sudo dpkg-reconfigure xserver-xorg.
sudo dpkg-reconfigure -phighxserver - xorg
xrandr --output lvds --mode 1024x768
I found one article that gave a three step process.
sudo cp /etc/x11/xorg.conf / etc/x11/xorg.conf.custom
sudo sh -c 'md5sum ' etc'/x11/xorg.conf > /var/lib/x11/xorg.conf.md5sum'
sudo dpk-reconfigure xserver-xorg.
Nothing gave me any of the results I expected from command doesn't exist to completely irrelevant menus. Start me from the beginning to what I should do. Yes I logged in properly with my username and password to. Do the 'etc' in the command need to be filled with something else like a drive letter or something. I'm so lost, should I disconnect my tv? Also I tried running in safe mode and it said something about display not found.

I just installed Lubuntu 10.04 on old PC (CPU: 700 Mhz, RAM: 640 MB). My swap partition is only 474 MB. I was told it should be twice my RAM, if that's true then I'm really low on swap space. Can I expand my swap space? I also have Fedora 13 installed, it has a 1.3 GB swap partition, can I have Lubuntu use this partition?

I have an Ubuntu server with no physical access to it, only via ssh/vnc.
It is stuck on a 1680x1050 resolution and in the system display settings the menus are disabled since there is no detected real display connected.
I need to lower the resolution to e.g. 800x600. code...

I am using OS 11.0 Every time I boot my laptop (dell inspiron 9300 - ati video M300). I get the desktop display as 1920 X 1200. This is too large for my default. I use KRandRTray to resize back to 1024 X 768. How can I set 1024 X 768 as the default but still have the option to go to 1920 X 1200?

Running new installation of 11.3 with KDE Desktop. I have sorted out text appearance and size thanks to pwabrahams in another thread but I have a big problem with screen size/resolution.
In previous installation of 11.1 on the same machine I was able to change the resolution of the graphics in order to fit the windows on the screen more comfortably. I used to use something like 1240 x 1048 but in the System Settings > Computer Administration > Display the resolution is set at 832 x 624 and no higher resolutions are offered.
I cannot find out the details of the embedded graphics controller (10 year old Dell PE6300 server) but the system information report it as ATI Mach64 GI with swrast (No 3D acceleration) version 7.8.2. I have spent several hours reading the many pages on graphics in this forum and have concluded that I should probably be using a legacy driver but have no idea how to change the driver. Of course if it were possible to increase the resolution to 1240 X 1048 without recourse to changing driver that might do it if I knew what setting to tweak.

I feel really stupid posting this, but I can't find what I am looking for. I feel like I have a decent understanding what is going on, but I am missing something very elementary. I have several mpc clientpro machines that are all in one's with 17" monitors built in. I can't get any resolution to fill the screen. I have been playing around with settings in xrandr, to no avail.
In windows xp it is usually ran at 1024x768 resolution which is supported. However there will be about 2 1/2 inches of blank space on the right side of the scree. and then another 2 1/2 inches of blank space on the bottom followed by about 2" of what seems to be a mirror of the top 2". I can change to several different resolutions all taking up different sizes of the screen, but nothing will fill it.
I understand I can't just do anything I like, like it would be unreasonable to expect the card to output 1920x1080. But can't I get it to at least fit the screen? Whether it was 1024x768 or 1152x864 or 800x600.
I have been searching and searching, and I think I am just simply misunderstanding a key term that is not allowing me to find more information on this. Something like panning, overscan, etc.

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 am using Fedora 11 and when the system booted, the screen resolution and font size were increased all of a sudden. Then I configured the screen resolution using
Quote:
system-config-display
to the actual that I had.
But the fonts in gedit are still big. Although the settings shows the default settings that I search on several blogs i.e.
Quote:
Edit -> Preferences -> Fonts & Colors -> Use the system fixed width font (Monospace 10)

I know that you can make it full screen, however it just makes the background OS's background black, and still provides a smaller display. Is it possible to make the guest OS's screen (or display) full size?

Have just upgraded from FC12 - nothing seemed to work as it should - to FC13 which is working quite a lot better - automatically updating everything etc. - and I can now install what I want. The preupgrade installation bizzo seemed to work quite well. But I can't seem to be able to set a "default" screen resolution - being slightly geriatric I like 832x624 - but rather have to do it manually every time I start the OS. Have dug into it quite a lot but can't seem to find a way of having it boot up each time at the res I want it to.
And also, in the past, when clicking onto URLs in emails in Thunderbird they automatically opened themselves in Firefox - but not now. Even clicking "Open in Browser" doesn't seem to do it. Have to copy and paste etc. Surprisingly the other way seems to work OK - "Contact:" tags in Firefox open a Tbird email pane. Do I have to get into about.config or write a user.js file or that sort of thing?

I was trying to run a program, needs high graphic, suddenly my computer crashed. I had to restart it, now the resolution has changed, I mean its the same as before "1024x768" but the screen has been widened, it looks like it has been stretched, and zoomed. I changed the resolution, but it didn't help.

My monitor is an old, low-res (800x600 resolution) flatscreen, and the loader keeps trying to set it for 1024x768.the initial setup and package selection screens ran fine. it was only after rebooting to the "Welcome" screen that the problems started. I found the "resolution= (800x600 for me) under "additional boot options", but I don't know how to use it.

My main computer died a-few weeks ago as a result I've been using my net book as my primary machine.By and large this has been alright. However I recently plugged my 17" monitor into it, it works fine but I can't get the resolution larger than 800x60. Which is non ideal for the larger display I'm currently using.Does anyone have any suggestions for getting the screen resolution higher.I'm running an Aspire One with ubuntu net-book remix.

I can't select default refreshing rate and resolution of my screen. Believe me, 50 Hz hurts eyes and causes headache. Ubuntu doesn't recognize my screen I used to work on 1280x1024 resolution with 80 Hz refreshing rate. 1152x864 60Hz is max I can select in Nvidia X Server and Ubuntu Screen Properties. I have tried changing options in Nvidia X Server, Ubuntu Screen Properties and tried xrandr commands (these ended with xrandr: Failed to get size of gamma for output default. or Can't open display).

I have installed Ubuntu 10.4 on Virtual Box, I have installed it successfully, the only problem is when I check the display settings it only have 2 options : 600 X 400 and 800 X 600 and this makes it difficult to work on Ubuntu as 800 X 600 is half the size of my desktop. How I can increase / configure the display settings so that atleast I can fit ubuntu screen into my screen size.
I did install the addition application, restarted the OS but still I don't see any display resolution 1200 X 800, tried pressing ctrl+D nothing happens, after installing I saw it updated mouse cursor now i don't have to press ctrl key again n again to enter into the ubuntu OS but still struggling with the resolution as it's too small, please guide me (here is the screen shot of my screen after installing the addition app).

I have Lucid 64 connected to my 27" TV with 4:3 aspect ratio via s-video from an nVidia NV4 GeForce 6200SE TurboCache 256 MB card using the 173 driver set at 800X600. After hours (don't get on my case, this is the first time I've had hardware that would run well on a TV) and hours of tinkering I've gotten a feel for how to do this and have some pretty good results. However, I have two problems.
.01 The display isn't quite filling the entire screen. It's leaving about a .25 inch black bar all the way around the screen. This is negligible and if I can't fix it with only minor adjustments then so be it. I can live with it.
.02 This one isn't so minor. Many of the Windows are opening with portions of themselves cut off of, usually, the bottom of the screen. This makes, among other things, getting to the Close button rather impossible.

In 10.4 I had set my default terminal size to my screen width - I type some long commands. After running an update this morning, my terminal comes up in the install default size. Using the preferences dialog, I cannot find the control to set the default width. Has it been removed? I hope I'm looking in the wrong place, but I have a chilling feeling that it's been dropped or perhaps just accidentally commented out.

I've been working on getting another OS installed on my computer for one of my classes (OS specific assembly instructions). To get this OS running, I had to start using a GPT rather than a MBR table. I backed up my Ubuntu partition (ext4) using the old-fashioned dd command. I've since been able to get everything working again after a dd restore.
The problem is that my original Ubuntu partition was only about 50GB and the dd image only takes up 40 GB. After I restored the image to the new drive (146BG), gparted is reporting 119GB used and only 26GB free. What can I do to reduce the size of my install to 40GB again?
When looking at the disk in baobab, it says the the filesystem is only 47.2 GB and that only 20.9 GB has been used. This is likely what the old partition's breakdown was. So my new question is: How can I make the filesystem capacity (47.2 GB) equal that of the partition that it is on (146 GB)?

I'm a faithful user of Ubuntu Linux, especially 9.04 Jaunty Jackalope. I have a problem with my screen resolution on my LG Flatron L1718S. It's a 17 inch and its recommended resolution is 1280x1024.I was on this resolution all along until now. Now I'm limited to 800x600 resolution. Here's what happened. Before installing Ubuntu 9.04 on a friend's computer, I put in his Seagate 40 Gig hard drive into his Intel Celeron Box with a 2.93 GHz and 512MB ram. I then plugged my monitor into his system. Upon booting, I discovered that the hard drive had a very strange looking operating system called OS2 Warp...seemed like Black XP to me. On the desktop, the icons were so big and bloated,the mouse was frozen, there was so much eyecandy which demanded so much graphics resources.
His graphics card is an onboard one, framebuffer. I then rebooted the machine, this time running the Ubuntu 9.04 live CD. Resolution still ok, with 1024x768 this time. I installed Ubuntu 9.04 and finished. I shut down the machine, unplugged my monitor and plugged it back into my machine, which is a Intel Celeron with a 2.4GHz processor, 1,5GB RAM, 80GIG X 2 Seagate IDE hard Drives, 2 DVD Drives, an LG Spermulti-DVD rewriter and a BENQ DC W2000 rewriter.My graphics card is NVidia GeForce NV34 FX5200 Series, 256MB RAM Graphics Card. Suddenly everything on the desktop is so large, and the maximum resolution now is 800x600. It becomes 640x480 if i add Nvidia drivers, version 173. If I switch over to Windows XP, Service Pack 2, I have no resolution issues there. Nvidia drivers are loaded there as well. No issues with resolution there. To test the screen again, I plugged my monitor back into my friends computer that I mentioned earlier on. The resolution is stuck on 800x600. After plugging the monitor back to my computer, I tried to edit the X.conf using "sudo nano", adding the desired parameters, like undetected screen resolutions, monitor name, device,etc, but nothing worked.
I always had to resort to the backed up configuration file for XOrg. The latest Ubuntu 10,04 Lucid Lynx picks up my monitor with a maximum resolution of 1024x768.The Mandriva One 2008 Live CD also gave me the same result like Ubuntu 10.04, this time giving me more higher resolution options. Strangely enough, from my Ubuntu 9,04 and older, after several tests, the resolution is still stuck to 800x600. When I press the AUTO RESET button on my monitor, the screen says "Processing image Auto Adjustment-For Optimal display, change resolution to 1280x1024". A factory reset did not help. The resolution was perfect until I plugged my monitor into my friend's computer, the one with the 2,93GHz processor. I took another friend's monitor, a HP Cathode Tube Monitor, a 17 inch as well, and plugged it to my machine to test the resolution. The results were glorious! All resolution options were shown, from the lowest "320x240" to beyond "1280x1024". Plugged it back to mine, the same result showed: 800x600 resolution, the lowest being 320x240. I kindly ask for advice on how I can be able to get all the screen resolution options available on my Ubuntu 9.04, like before, because it shows the maximum of800x600, lowest- 320x240 on "display" in "System--Preferences".

I have fedora 13 set up on a HP6715S laptop. Runlevel 3 is a problem, because the capital letters are the size of full stops. Reading a little, I can try a grub vga setting, but I am not keen as my screen is 1200x800 and X cannot set it otherwise, so I doubt grub could. There's KMS for radeon cards, and the kernel can do what it likes. The biggest font supplied with fedora is sun12x22, which doesn't even have a euro sign. I gather I can go to a height of 32. Anyone know of larger consolefonts, or a wheeze to double the size of one of the others, e.g. lat9w-16? setfont-h32 increases height, but not zoom, so it's like a double spaced console.

I use a program which makes a large image which I have to scroll to view. The program has no way to save the image, and I have no access to the source to modify it. The only way I have to get the image from the program is by screenshot. My goal is to save the full size image without having to piece together individual screenshots. I'm using this script to try taking a screenshot:
#!/bin/bash
window=$(wmctrl -l | grep "Program$" | awk '{print $1}')
wmctrl -v -i -r $window -e '0,0,0,6030,5828'
wmctrl -i -a $window
import -window $window ~/Desktop/screenshot.png
This uses wmctrl to get the window id ($window) for a window named "Program". It then tries to resize the window to the desired dimensions. It uses imagemagick (import) to save a screenshot.png on the user's Desktop. All of this works except the resize step. I can resize the window using wmctrl -r -e, but sizes greater than the screen size don't work. I'm using Ubuntu 10.04 and the Gnome Desktop. I run two monitors, but I've tried this with one of them disabled. Is there a way to resize the window larger than my screen to get a huge screenshot?
Part II: I tried using xrandr to set up screen panning, so as to have a bigger desktop than my monitor. xrandr --output LVDS --panning 2600x2500 This command makes the laptop screen pan over a 2600x2500 size desktop, even though it can only show 1440x900 at one time. To turn off the panning, I can use a similar command to set total size and with zeroes for the panning section. This gives me back my original laptop display behavior. xrandr --fb 1440x900 --output LVDS --panning 0x0 This is all done with xrandr, and does not require any Xorg.conf changes (my Ubuntu system doesn't even have an Xorg.conf).
My video card seems to only allow about 6.5 million pixels, even though the maximum dimensions are 8192x8192. That maximum seems to be the maximum for either dimension, but there is a limit to how many pixels can be drawn, which is the width multiplied by the height. Once I did the screen resize, I tried my script again and got a screenshot. The screenshot however is totally scrambled. I'm not sure if it's unable to take a screenshot of an off-screen window or if it is unable to handle the large dimensions of the window. With the panning display, the window should think it is visible, and the window manager should think it is on-screen. So there is a pixel buffer somewhere with those pixels in it, so there should be a way to get a screenshot.
