Debian Hardware :: Can't Change Resolution Or Set Dual Display
Jul 4, 2014
I have wheezy installed on my laptop with XFCE 4.8 and kernel 3.14 from backports. The laptop uses Nivida-optimus:
Code: Select all00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06)
01:00.0 3D controller: NVIDIA Corporation Device 1292 (rev a1)
I installed the proprietary bumblebee-nvidia (version 3.2.1) as per the instructions in URL...The problem is that when I connect a monitor to the laptop, the image is duplicated with only part of the screen showing on the second monitor. The monitor itself is not detected in the display settings or arandr / xrandr, so I can't change the resolution or set dual display, etc. Here is the output of xrandr:
Code: Select all$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 1920 x 1080, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
1920x1080 0.0*

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.

(Video card is a nothing special Nvidia)
I want to change the default resolution of 1280x1024 to 1024x768. Setting at boot using the space bar or the KDE display (personal settings) does not survive the next boot. In yast or yast2, hardware, there is no monitor selection (something wrong here?).
Using root, run level 3, the command sax2 --vesa 1024x768 does nothing.
or sax2 -m 0=fbdev does nothing.
I had no problem with previous suse releases. What am I missing?

I am on Lucid 10.04 with Nvidia 9600m (v195.36.24) My TV is 1280x720, my Laptop is 1600x900 (Closest setting to the TV is 1360x768 ). I plug my laptop to my tv via an HDMI cable. I press F1 to get into my presentation mode, and the tv shows most of the desktop, but not all of it. Is there any way to conveniently make it so it automatically sets it to 1280x720?

I recently purchased an iMac 27" i7 with 8GB RAM, however after i installed UBUNTU i can't seen to find a way to set my display resolution to 2560 x 1440.
This is my second try on UBUNTU, the first time i was happy but disappointed on how difficult changing settings could be, this time seems not to be any different.

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 just installed Ubuntu 9.10 this evening. I have a Nvidia Geforce 8500GT video card with two monitors hooked up (one to the cards VGA, the other to the DVI). I installed Nvidia drivers and Ubuntu is working with both monitors fine.
The problem I am having is it chose the monitor plugged into VGA as the primary (uses that monitor for the toolbars) when I really want them to go on the monitor that is plugged into DVI. Is there anyway for me to switch which monitor Ubuntu treats as the primary?

Recently when I rebooted the display resolution went to 800x600, where as before it was 1024x768. For some reason 1024x768 is no longer listed in (GNOME) System->Preferences->Moniters. Even after reinstalling Debian from scratch it's not there anymore. What can I do to fix this? System->Preferences->Moniters says Moniter: Unknown and stays that way even if I click Detect moniters.

How can I know the display resolution (e.g. 1280x1024 px) without starting X?I mean: let us suppose that /etc/X11 was renamed to /etc/x11. After reboot Debian starts in text mode only.

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.

I've decided to try Debian Lenny, after i succefully installed it without any problems there appears to be a problem - after loading the services and etc, my monitor turns off with a floating message saying it cannot display the current resolution, and that i should set it to 1280x1024@60Hz.

I have a brand new computer with an ATI Radeon HD5850 video card I have a LCD monitor with a native resolution of 1920x1080. I installed Debian Testing 2.6.32-5-amd64
Because I have several machine, I use a KVM (switch keyboard) in the middle. This KVM is quite old but still work correctly only problem is that it don't forward the EDID information. Until now it wasn't a problem, and by specifying the correct parameters of the monitor in /etc/X11/xorg.conf , I always succeed to reach the 1920x1080 resolution
In installed the proprietary drivers from ATI Catalyst 10.6 (last version)
since I have 2 problems :
first in the console I used framebuffer in 1280x1024x32. Before installation of the ATI drivers, it was ok, now the screen is completely black !! on every tty (I didn't investigate much on this trouble yet)
Second problem:
I can't reach the native resolution of my monitor ! No matter what I'm doing, the best the driver propose is 1600x1200 !!
I made a lot of test and modification in xorg.conf but without success, it always goes back to this resolution and never propose something higher For information, if I connect the monitor directly to the video card (removing the KVM), everything is OK and the resolution is automatically set to 1920x1080

I have a nVidia GeForce GTX 760 Ti Graphics card. I have installed the proprietary driver and disabled the open source one. The problem is when I connect to two monitors via DVI and VGA, the VGA one appears to be 'unknown' and is using incorrect resolution of 640x480. How can I correct its resolution?

After spending the last couple of days running different distros on a old Compaq armada 7800 I've settled on Debian, as it's recognised most of the hardware with out to much tinkering
Only problem i have is the display resolution i need to run at 1024 x 768 but the max i can get is 800x600 I believe the display adapter is a S3 Virge/MX 2D/3D Dual Display Accelerator
Is there a driver/package I can download to correct this issue
I can use the console as long as some one give me Janet and John instructions

Everything runs fine out of the box with Debian 7.2

playing with debian I find that I have no answer when I try to resize my console if I wish to use it without a GUI. Are there something that could resize the screen ? In this moment it seems to be 640x480 and it could be better if the resolution could be 800x600. I have tryed to modified /etc/grub/00_header
if [ "x${GRUB_GFXMODE}" = "x" ] ; then GRUB_GFXMODE=800x600 ; fi

Ever since I installed Debian, my monitor keep saying: "Input Signal Out of Range Change Settings to 1600x900 - 60Hz". So I thought it a problem of the screen resolution, so I have been trying to edit my xorg.conf file, but it doesn't seem to work at all. And this is my settings.

I searched the archives and didn't find anything on this, and was just wondering if there is a problem if you load Ubuntu 9.1 and have a display that's higher than 1024x768. I'd prefer a machine with a higher res, but I've heard that Ubuntu will only go as high as 1024x768.I'm guessing, however, that by 9.1, it should recog the higher res while loading and it won't be a problem, but thought I'd check before shelling out on a machine with a nicer display.

I have a fresh installation of Debian 7.8 on my Dell Precision notebook. Somehow I failed to configure Xorg in a proper way. I do have X up and running, but I can not change my monitor resolution. Here is my graphics card.
Code: Select all$ lspci | grep VGA
00:02.0 VGA compatible controller: Intel Corporation Haswell Integrated Graphics Controller (rev 06)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Radeon HD 8800M Series
I tried to follow suggestions from Debian Wiki, somehow nothing really worked (https://wiki.debian.org/AtiHowTo)
Code: Select all# aticonfig
aticonfig: No supported adapters detected
Code: Select all# X -configure
Terminated with an error, below is the Xorg.0.log file

I just bought a Logitech 570 trackball. I feel as though the resolution may be set a little low. How do I change mouse resolution under Linux? I do have lomoco btw, but when I use the command lomoco -8 it says the device does not support writing a new resolution to it. Basically wondering if theres a text file somewhere where I can just change the default mouse resolution.

Now that I'm more lucid I can adjust the format a bit. If I try opening the TTY the screen goes completely black after visualizing few artifact on the bottom of the screen.
Pressing Ctrl+Alt+F7 brings me back safely to the GUI
So far I tried to modify the /etc/defaults/grub file to uncomment the grub resolution and the grub_terminal to no avail. Now at least it seams to waste some less time to load the grub (it took something like 15 sec before) but it lost the previous green/torquoise background and now it's white char on black background.
On a side note pressing C on the grub to reach the grub console gave me some answer I don't know how to deal with... I was trying to use vbeinfo but it didn't found the command and so I tried the insmod:
Photo(large) of the complete grub console session wrote:grub>
grub> videoinfo
List of supported video modes:
Legend: mask/position=red/green/blue/reserved
grub> videotest
error: no suitable video mode found.
grub> insmod vbe

Well I have installed lenny from netinstall, with Xfce on a virtual machine, everything runs smooth and I really like how does it work, I just have a little big problem, the resolution is too high, it is higher than the host resolution, if I have to work in the down part of the screen I have to scroll down in host, it is kinda annoying, under screen config (right click>configuration>screen config) for resolution only the default option is available. I have googled and I have found that /etc/X11/xorg.conf must be modified to use another resolution, but I'm not sure of what to change or what to do exactly.
