Ubuntu :: Set Monitor Size When Xrandr Doesn't Offer It?
Jul 16, 2011
I am running ubuntu 11.04. I am able to set my screen size to 1600x1200 in windows but ubuntu doesn't offer me that size in xrandr, though it says my maximum size is 4096x4096, I have posted my xrandr results below. What do I do to set my screen to the higher resolution?
Screen 0: minimum 320 x 200, current 1280 x 960, maximum 4096 x 4096
VGA1 connected 1280x960+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1024x768 60.0
800x600 60.3 56.2

When I'm connecting second monitor to the laptop, Display Settings applet (and xrandr -q) does not detect full list of supported resolutions. I need to restart my system or perform Log off while monitor is connected to make full list available.openSUSE 11.4 32 bit, Ati Mobility Radeon HD 3450, proprietary ATI driver 11.3 8.831.2-110308a-115935C-ATI.External monitor is FullHD SyncMaster B2330 (1920x1080)I wonder is there any other workaround to access full resolution that does not require restarting of the system?

i tried updating ubuntu from 10.10 to 11.04. It didn't work out, i got just a black screen trying to load new ubuntu. Nevermind, after multiple tries to recover it i simply installed ubuntu 11.04 over it. It works fine now, but i already got some problems Mainly, i can't find a way to pick the appropriate resolution. I have a 19" monitor with 1280x1024 resolution, video card is nvidia 8500gt. Any GUI tool (nvidia driver settings or 'monitors' tool) doesn't allow me to pick what i want. xorg.cong is nearly empty, that's all what i have there
Quote:
Section "Device"
Identifier "Default Device"
Option "NoLogo" "True"
EndSection
I did some google searches and found out about Xrandr (i'm not much a techy really). That's what i get running xrandr in the terminal

I have two monitors, my laptop screen, and an LCD monitor. I want to configure linux to put one virtual desktop on one, and a second on another. I'm using Compiz as well, so I'd like it to show one side of the cube on each monitor. I'm not really sure how to go about setting this up though. My attempts so far have stretched the same desktop across both monitors, or resulted in an unusable monitor that just sits there with the default background. While I was trying to figure this out I came across something called XRandR that lets you connect/disconnect monitors without restarting xserver. I'm not sure how to get this going either, the only tutorials I found were for intel chipsets, and I'm using the proprietary NVidia drivers.

I ran the following commands on my ubuntu desktop :
xrandr --output VGA-0 --mode 1680x1050
xrandr --output VGA-1 --mode 1680x1050
xrandr --output VGA-1 --left-of VGA-0
This gives me dual head. I have a second machine on the same 100mbps network that is also running Ubuntu. I want to run X on that machine and have it's X session as a monitor in xrandr, so I would add something like this :xrandr --output REMOTE-1 --right-of VGA-1Is this possible?

Problem is that Ubuntu installation program doesn't want to "offer" Dual-Boot option on my main HDD. Only format option and manual partitioning.

I was trying to add a new resolution mode to my monitor, but XrandR always fails. These are the steps I follow:
Quote:
$ gtf 1280 768 60
then I copy the result and type
Quote:
xrandr --newmode "1280x768_60.00" 80.14 1280 1344 1480 1680 768 769 772 795 -HSync +Vsync
[Code]....
Finally I just can't create another resolution. And yes, my monitor should run in 1280x768.

I have a display problem since updating to Slackware 13.37. Everything was fine on Slackware 13.1, but when I switched to 13.37 some piece of software came up with the wrong monitor size. I have a 1600x900 LCD monitor but the X screen came up as 1024x768 with blackness on either side of it. Under Slackware 13.1 the X screen came up as 1600x900 as it should without any prompting from me; I didn't even have an Xorg.conf file. I tried using the Xorg.conf file which was needed and work for older Slackwares, eg 12.*, but it didn't work. (Saying it didn't work is a gross understatement! That old Xorg.conf completely screwed up mouse, keyboard, and monitor; the screen was flashing and nothing worked. The only way to get control back was to SSH into the machine from my laptop and reboot. Killing the X server via that SSH console did NOT the flashing or get me back to my console login; only reboot worked.)
I find I can get the screen to be the right size manually by going through KDE's "System Settings" --> "Display and Monitor" --> "Size & Orientation", then disabling "LVDS1" and setting VGA1 to 1600x900. The size of my odd-sized monitor is being correctly detected for the "Auto" choice. Upon reboot LVDS1 stays disabled but VGA1 reverts to 1024x768 so I have to do this each time.I've done some search of the on-line literature regarding the error messages I am seeing in the boot log.
People are suggesting changing all kinds of things to alleviate the side effects of the "conflicting" error message above, even modifying GRUB parameters (which won't work for me since I use LILO).So, I have a manual work around which I must do each time I log in. Does someone know how I can get X or KDE to force 1600x900 upon start (while Linux/X/whoever find and fix the problem) or does someone know of a real fix?

I just switched from Ubuntu to Debian and I am having trouble doing something that I found easy to do with Ubuntu. I have a Radeon R9 graphics card from MSI with dual DVI ports and I'm trying to get xrandr/arandr to detect my dual monitors but it only detects one. I've installed all the drivers and even installed the "amdgpu" driver from the Ubuntu repository but still not detecting. What drivers am I missing?

I am running Fedora 12 on a T400 Thinkpad. When connector my external monitor prior to powering on the computer or if I restart it, I get a lot of resolution choices from xrandr. See below.
Code:
$ xrandr
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 8192 x 8192
LVDS1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 303mm x 190mm
1440x900 60.0*+ 50.0
1024x768 60.0
[Code].....
Is there some daemon I need to restart to detect the monitor resolutions correctly, or is there a module I can reload?
There seem to several variables to reproducing the behavior. If I restart without the laptop without the monitor plugged in, log in, and then, plug the monitor in with the monitor powered on prior to plugging, all resolutions are detected properly. However, if I plug the monitor in with it powered off, then power it on, I only get the few options shown in above. Once I get the reduced number of options, it seems to stay that way till I restart regardless of how I unplug the monitor.
I have found a work-around by just forcing the modes with xrandr --newmode and xrandr --addmode, but I would much rather have the modes autodetected.

I'm trying to hook up my TV to my MacBook1,1 laptop running the Lucid Lynx Beta. The TV is connected to the laptop via a mini-DVI to DVI-I adaptor, which is connected to a DVI-I to video adaptor, and this is connected to the TV via a component cable.
Under OS X, after plugging in the mini-DVI cable, the TV automatically becomes a secondary display for the laptop (extending the current screen), so from a hardware perspective everything seems ok. Under Ubuntu, plugging in the mini-DVI cable elicits no response from XRandR whatsoever (xrandr -q reports DVI1 disconnected both before and after). URandR and the regular "Detect Displays" button in the "Monitors" preference app do nothing. The laptop has an Intel GMA 950 chipset, and the Intel driver is running successfully (Compiz works fine). I have a clean xorg.conf (generated by X -configure), except for the addition of "Virtual 2048 2048" in one of the SubSections of the Screen section. I'd be happy to post the full xorg.conf if it would be useful.
So far I have tried xorg.conf tweaks, and I have followed instructions to manually tell xrandr to output to DVI1 as described in the comment by Marko Mikulicic here.

I installed Karmic on an older PC I had laying around, and the only trouble I am having is with screen resolution. It uses an old ATI chipset (onboard) for video, and it doesn't seem to do EDID correctly, so I can't display anything higher than 800x600. I have tried creating an xorg.conf, but it's still not working. How can I tell Xorg to ignore the fact it can't detect a widescreen monitor and display something larger than 800x600? I noticed the log says the sync's are out of range, but I am not sure how to fix it.
Here is my current xorg.conf.
Code:
Section "ServerLayout"
Identifier "X.org Configured"
Screen 0 "Screen0" 0 0
InputDevice "Mouse0" "CorePointer"
InputDevice "Keyboard0" "CoreKeyboard"
EndSection

my mediacenter is attached to an beamer with the optimal resolution of 1280*720 ubuntu 10.04 doesnt offer me this revolution (on my intel 915 graphis controller). this means i have to add this resolution to the possible resolutions. first i used cvt
Code:
cvt 1280 720 60
and got this result:
Quote:
# 1280x720 59.86 Hz (CVT 0.92M9) hsync: 44.77 kHz; pclk: 74.50 MHz
Modeline "1280x720_60.00" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
then i added this to xrandr
Code:
xrandr --verbose --newmode "1280x720" 74.50 1280 1344 1472 1664 720 723 728 748 -hsync +vsync
and
Code:
xrandr --verbose --addmode VGA1 1280x720
now i can select and use the new resolution - until next reboot. after an reboot 1280x720 is again not available. even if i work with sudo - the resolution isnt there....

The image on my external monitor is blurry. the resolution is right, but the Monitors menu shows the monitor to be a 20" while it is actually a 19". So this may be a hint. I would like to know how to adjust the monitor size (if possible). How can this be done? I am running 10.4 on a dell precision 4400, connecting with the monitor via VGA.

I was getting low disk space notifications so I used LVM to increase Ubuntu's volume from 10GB to 50GB. LVM and Disk Utility show the correct new size, but System Monitor and the Properties of the File System (in Nautilus) show the old, smaller size. Do I need to update something to get them to see the new size?

After getting tired of squinting at my netbook screen (System 76 Starling) I bought a 21.5" Asus VE228H monitor. It works beautifully with the right resolution and aspect, EXCEPT that the driver Ubuntu is using is for a 22" monitor, and the image on the screen has about 1/8" missing all around. Sadly, this eliminates the menu bar at the top of the screen. Moving the image down doesn't help. Is there any way to shrink the image, or get Ubuntu to use a driver for a 20" or 21" monitor instead of 22"? I've been using computers since DOS command line days, but have been using Ubuntu only about 2 months.

I am using Kubuntu Amd64 Lucid on my desktop and I have allocated 08.03 GB partition for swap. But today I have noticed that system monitor is showing this as 09.90GB which is incorrect.
I tried deactivating the swap from KDE Partition manager. Even after deactivating swap it still shows the swap as 1.9 GB. So there is clearly 1.9 GB swap added to my system. I am not sure how. Attached screen shot clearly shows the system monitor issue. One possibility is, I have 4 GB (3.7 asper system) RAM comprising two units of 2 GB cards. Is this 1.9 GB read from one of these? I tried to boot the system from Kubuntu AMD64 live CD and then it showed only 8 GB as expected. So not sure whats causing this issue in my installation.

I've a high resolution monitor(2560x1440) on my laptop running Debian testing and would like to change the font size in X. I manage to change most of the fonts to a readable size through the openbox configuration manager. But the font in my login window and for example in apps like vlc is still very tiny. How this could be changed ....

I am looking for a utility that would do the following:1. Be run manually on a list of files whose sizes should not change, to get a control file containing the sizes of each file.2. Subsequent manual runs would report any changes in size of any of the files in the list, and allow option to accept the new sizes.3. Be run as a cron job to check for changes in the file sizes and send an email alert if a change has occurred since the last time it was run.The purpose is to detect possible hacks of key files on a website. It would not include files expected to change, but just those that should not change. It would be run manually a few times to get the control list one wants to monitor.

I've been running 8.04 for a long time w/o problems. However, videos tended to hangup, as if waiting for more data. I have a Nvidia GeForce 8400 GS graphics card, so I attempted to load the latest driver. That landed me in Low Graphics Hell, where I couldn't change the resolution (even when a better one was offered) because I couldn't get to the bottom of the screen to get to 'Apply.' I had down loaded 10.04 and burned a couple of CDs, and I attempted to upgrade. But neither the Update Manager or CD worked because I couldn't get far enough down the update screen. After a long struggle, I have a reasonable resolution, with the Nividia x server running.
Now, when I try to up date, 10.04 is no longer offered to me, either by the Update Manager or the CD. Apparently, I've used up all of my chances to upgrade. What now?

I'm currently running 10.04. Great OS! However, the one small thing that annoys me is with the software centre, it doesn't tell you the size of the download. I know this probably doesn't bother people if you've got 50mb internet and unlimited downloads, however, I have 3.5mb, and a download limit!
Is there A) anyway I can get software centre to tell me the size of a download, and B) is this altered in later versions - due to my limit I don't want to download them to see - catch 22!

I am running Ubuntu 10.04LTS (64bit) and the drives are formatted as EXT3. I have a Raid5 that had 4 x 1TB drives. It is mounted as my /home. I added a 5th Drive and used the Disk Utility to Expand the array. In the Disk Utility it shows as 4.0TB RAID5 Array, however when I open a console and type df -h it still only shows at 2.8TB (Which is the size of the 3TB array I had previously.) What do I have to do to have the 4TB array show up properly? I'm obviously missing something, but I'm not sure what it is.

In trying to solve a friend's lack of foresight, i have currently disabled my system.
I was using dd_rescue to make a copy of a drive with a corrupt and unfixable Partition Table. I was a fool, and had a drive mounted to /media/Storage, but ran the backup to /media/storage.
Thus, dd_rescue completely filled my primary drive before informing me that there was a problem.
I don't really trust myself with command line work, so I foolishly sudo'ed nautilus and deleted the folder /media/storage.
Unfortunately, I didn't realize it, but the available space on the drive still read 0bytes.
I tried Terminal work to do a sudo apt-get clean command, but for some inane reason, the laptop screen won't support the display setting for the Terminal login, so I just had to hope that I was doing it right.
I wasn't, and decided to try working from a Live CD so I could see what I was doing.
the folder /root/.Trash/ doesn't exist on Ubuntu's install drive, and I can't figure out why the properties of the drive say "contents: 241310 files, 3.7 GB" but also "Total capacity: 52.8 GB. Free space: 0 bytes"
Any suggestions on how I can get this to shake out?

The Compiz Setting page for Unity will not let me set the launcher to autohide or other hiding option, and the Experimental page will not let me reduce the icon size. The lack of hiding is another as the left edge of windows can disappear under the the Launcher.
