Ubuntu :: Add A New Resolution Mode To Monitor But XrandR Always Fails

Oct 12, 2010

I was trying to add a new resolution mode to my monitor, but XrandR always fails. These are the steps I follow:


$ gtf 1280 768 60

then I copy the result and type


xrandr --newmode "1280x768_60.00" 80.14 1280 1344 1480 1680 768 769 772 795 -HSync +Vsync


Finally I just can't create another resolution. And yes, my monitor should run in 1280x768.

Hardware :: Limited Resolution Choices In Xrandr With External Monitor On Hotplug?

May 5, 2010

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.

$ 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


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.

OpenSUSE Hardware :: Xrandr Doesn't Detect External Monitor Native Resolution

Apr 25, 2011

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?

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:

Debian :: How To Set Display Resolution When Xrandr Cannot Work

Sep 19, 2015

I've just completed my first pc build, and installed Ubuntu 8.2. My build was focussed around a legacy Apple Cinema 30" display, which has 2560x1600 @ 60fps resolution. The motherboard - Gigabyte H97N-Wifi - supports that display, although the display drivers are supplied by Intel, and are therefore nonfree. On startup, my display resolution defaults to 1200x800. This is what /var/log/Xorg.0.log says about it:

Code: Select all[snip]
[     1.830] (II) intel(0): Output VGA1 has no monitor section
[     1.881] (II) intel(0): Output HDMI1 has no monitor section
[     1.882] (II) intel(0): Output HDMI2 has no monitor section
[     1.882] (II) intel(0): Output HDMI3 has no monitor section
[     1.933] (II) intel(0): EDID for output VGA1
[     1.986] (II) intel(0): EDID for output HDMI1
[     1.986] (II) intel(0): Manufacturer: APP  Model: 9232  Serial#: 33555281


I bumped into a webpage which stated that xrandr does not work with proprietary drivers, and if that's true, I can't get it to change resolution on my screen.

Ubuntu :: One Virtual Desktop Per Monitor / Using XRANDR

Mar 14, 2010

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.

Ubuntu :: Remote Machine Should Be Third Monitor In Xrandr?

Jan 10, 2011

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?

Debian Hardware :: Missing Mode Into Xrandr

May 6, 2014

I have a notebook Asus X-serie with a

Code: Select all# lspci
00:00.0 Host bridge: Intel Corporation ValleyView SSA-CUnit (rev 0c)
00:02.0 VGA compatible controller: Intel Corporation ValleyView Gen7 (rev 0
00:13.0 SATA controller: Intel Corporation ValleyView 6-Port SATA AHCI Contller (rev 0c)
00:14.0 USB controller: Intel Corporation ValleyView USB xHCI Host Controll (rev 0c)


However I would like to display the same too onto my CRT. My crt of my pc notebook is blank. Nothing. I read a lot and nothing. I read on xrandr but few info:

Adding new modes

Under some circumstances, some modes might be missing. For instance, if the monitor does not report correct EDID information. Or if the output didn’t have a CRTC available at startup because another output was using it and you disabled it in the meantime.

If a mode exist, you may add it to one output with:

$ xrandr --addmode VGA1 800x600

If the mode does not exist, you may first create it by passing a modeline:

$ xrandr --newmode <ModeLine>

Software :: Xrandr Not Changing The Resolution (Debian Lenny)?

Jan 1, 2011

GNOME decided not to use the correct resolution ever. In Ubuntu, it got it automatically and that said it should be 1366x768, and when i run this:


xrandr -s 1366x768

I get


Size 1366x768 not found in available modes

So then I tried to run xrandr and find out what was available and I got:


$ xrandr
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
default connected


So when I try to change it to 1024x768, I get the same "not found in available modes" message.

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

Hardware :: Finding The Maximum Supported Resolution Of Video Card By Using Xrandr?

Aug 25, 2010

I am trying to find the maximum supported resolution of my video card by using xrandr. My card is an NVidia GeForce Go 7300 (in a laptop). The official documentation does not list specific resolutions that are supported. My laptop display is detected as "AUO" in the NVidia X Server Settings dialog (Ubuntu 10.04 amd64) and has a native resolution of 1280x800. However, I would like to know what is the maximum resolution that I could use on a display with the VGA adapter irrespective of whether the laptop's display is on. This is what I get from xrandr: Screen 0: minimum 512 x 384, current 1280 x 800, maximum 2304 x 864 default connected 1280x800+0+0 0mm x 0mm

1280x800 50.0* 51.0 56.0 52.0
1024x768 52.0 50.0


I am guessing the maximum width of 2304 would be for using TwinView with the laptop's 1280-width display next to a 1024 CRT or similar. Surely these cannot be the only supported resolutions. I would like to use a LCD display of width somewhere around 1600 pixels (in particular while turning off the laptop's screen so as to use the external LCD as the primary display) if possible.

Debian Multimedia :: How To Get Xrandr / Arandr To Detect Dual Monitor

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?

Ubuntu :: Out Of Range Resolution And Recovery Mode?

Sep 30, 2010

I decided to install ubuntu on my family desktop because it is quite old now and it needs constant maintenance for windows. I have used the old ubuntu on this computer some time ago i believe it was the 8.04 version. But anyway back to the point, i have decided to put ubuntu back onto the computer but i have encountered an issue. The issue is that when i installed ubuntu everything seemed to be working perfectly out of the box the printer, wireless etc... but when i installed the restricted drivers for the ati card inside.Upon loading ubuntu a big OUT OF RANGE came up on the monitor and i cannot access anything. I looked at the FAQ but am unable to get into recovery mode to type in the relevant command prompt and there seems to be no grub popping up to press esc/shift to get into the menu. Is there anyway around this? i am prepared to reinstall ubuntu but what could i do to prevent this upon re installation?.

Ubuntu :: GRUB2 Resolution - Cannot See The Recovery Mode Menu

Apr 24, 2011

I recently reinstalled Ubuntu 10.04. Since I did that I have had a problem with GRUB: I cannot see the Recovery Mode menu - at least not anything intelligible.

I can see the normal first GRUB menu with all installed operating systems, recovery modes, and MEMTEST, etc, but cannot see the Recovery Mode menu. What I do notice (if I select it) are some fuzzy lines at the top of the screen. I also notice the Ubuntu splash screen does not appear any more either.

Clearly it seems there is a resolution issue. I have a 1440 x 900 monitor and the current version NVIDIA driver.

This happened some time ago on previous Ubuntu releases, but was not an issue when I originally installed 10.04.

Attempted Fix:I installed the StartUp-Manager and have tried all the resolution combinations with no success. Some yield bigger more centrally displayed fuzzy lines, but still nothing legible.

Although this isn't "life-threatening" I'm just a bit worried that I might need the Recovery Menu and not be able to use it.

Ubuntu :: How To Freeze Monitor Resolution

Jul 25, 2011

Just installed 11.04 on a box that it is on a kvm switch. As long as the switch is connecting the monitor to the booting Ubuntu box, the resolution of the monitor is detected OK. However, if for some reason I am working on a different box and the KVM switch is routing K V and M inputs to the other box, then Ubuntu defaults to what seems a botched VGA setting (i.e. it chops off top and left sections of the display).While in this "VGA" mode if I log out and log in, it re-detects the resolution ok.Is there any way to force Ubuntu to use a specific resolution no matter what? In this way, if I am working on a different box while waiting for Ubuntu to load, when I switch the resolution will be OK.I tried the only thing I can think of and this is to set the "good" resolution as "default" for "all" monitors, but it has no effect.

Ubuntu :: Increasing The Monitor Resolution?

My monitor supports up to 1440*900. When I selected one of the higher resolutions, it didn't look very sharp, and the text was somewhat fuzzy and lacked clarity. Was this rendering being done by the graphics card but 'compressed' by the monitor?

The status said 'switched to metamode'. I tried searching but found nothing - what exactly does MetaMode mean? I'm more interested in understanding what was happening, only experimenting with the higher resolutions. What monitor and resolution do you have?

Ubuntu Networking :: Wireless DNS Resolution Fails?

May 24, 2011

When connecting to any wireless network, DNS lookups completely fail to work. Over a wired connection, there's no trouble.

I can ping machines by IP address, and I can dig and nslookup domain names using the DNS servers assigned by Network Manager or by myself. When I try to ping by domain name, however, nothing happens. Similarly, I cannot ssh into machines by domain name or browse the web.

My wireless card (Intel 4965AGN) is managed by Network Manager. The issue is seen regardless of whether DNS servers are obtained automatically by DHCP or assigned by me through Network Manager. This started about a month or two ago while I was using Maverick and presents again with Natty. I dual-boot Natty and Windows 7, and everything works fine in Windows.

Somehow, this seems to be linked to Nautiluswhile connected to a wireless network, Nautilus won't open, my desktop icons won't show, all that jazz. If I'm connected to a wired connection at login time, Nautilus works fine.

I've managed to workaround the browsing issue by setting up an ssh tunnel through a machine at school and forwarding Firefox's DNS resolution through that tunnel. But I'm at a loss as to how to resolve the core problem.

Here's some diagnostic info. I've modified my IP and hardware addresses below.

$ ifconfig wlan0
wlan0 Link encap:Ethernet HWaddr 00:1f:3b:27:be:35
inet addr:xxx.xxx.38.96 Bcast:xxx.xxx.39.255 Mask:
inet6 addr: fe80::21f:3bff:fe27:be35/64 Scope:Link


I've tried all the basic steps killing and restarting Network Manager, renewing my DHCP lease using dhclient, restarting /etc/init.d/networking. I'm at the end of my rope, though, and ready to reinstall. I'd be much obliged if anyone can think of a less "Microsoft" solution.

Ubuntu Multimedia :: Add 320x200x8 Resolution/Mode To Xorg.conf?

Oct 1, 2010

I am trying to run using WINE. It has a platinum rating on the site, and runs perfectly on my laptop.on my desktop it doesn't seem to run at all.The screen goes black,then brings me back to the desktop. I manually ran the WINE command in the terminal, and it produced the error "err11settings:X11DRV_ChangeDisplaySettingsE x No matching mode found 320x200x8 @0! (XRandR)". The laptop and desktop are both running the same version of WINE (1.3.3) and have similar Nvidia cards (laptop has a mobile 9600, desktop has a 9800). I found a bug report on this exact issue on the WINE website (I'll paste a link), and they mention that the solution is simply to add the 320x200x8 resolution mode to Xorg.conf.

I've tried generating the line that I may need with a web-based modeline calculator, referenced on another thread, but it caused my system to fail booting. Luckily, I backed up xorg.conf before making changes and restored the old one via recovery mode. Here's the link to the calculator, I may just be using it wrong: [URL]
