Debian Multimedia :: Cannot Set External Monitor To Higher Resolutions
Jul 8, 2011
I recently got a new external monitor for my laptop, and connected them by VGA. This is what 'xrandr' tells me:
Screen 0: minimum 320 x 200, current 1440 x 900, maximum 4096 x 4096
LVDS1 connected (normal left inverted right x axis y axis)
1280x800 60.0 +
1024x768 60.0
800x600 60.3 56.2
640x480 59.9
VGA1 connected 1440x900+0+0 (normal left inverted right x axis y axis) 510mm x 290mm
1920x1080 60.0 +
1600x1200 60.0
1680x1050 60.0
1280x1024 75.0 60.0
1440x900 75.0 59.9*
1280x960 60.0
1280x800 59.8
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
However when I try to change to some of the higher resolutions, such as 1920x1080, all I get is a corrupted and flickering image. As indicated above, I am currently on 1440x900@59.9h,z but for some reason 1440x900@75hz doesn't work. The same seems to be true for 1280x1024. The three resolutions above that all cannot be selected properly. I tried setting the resolution to maximum in Windows XP and it worked, and my video games console can set it to 1080p, so I don't think there is anything wrong with the monitor. Is there anything I can do or is this some kind of bug or limitation of the graphics driver or something? The graphics chipset of the laptop is an Intel 945GM, which I believe should be capable of displaying 1920x1080. I am running debian unstable with what seems to be the most up to date version of xserver-xorg-video-intel.

I've got a little problem with my 9" netbook. It came preinstalled with Ubuntu (factory install), but I reinstalled it to get a fresh karmic as it was a second hand.The problem is, whenever I plug in an external monitor, rightclick on the display icon and click "Configure Display Settings..." both monitors go black and nothing responds. Weird thing though, is that sometimes the mouse appears on the second monitor. I need a solution for this, either creating a xorg file (I have no clue on how to do that) or some other solution that works.
My netbook resolution is 1024*600, the external monitor resolution is 1024*768. It should be noted that I had a similar problem on another Ubuntu laptop (NVIDIA drivers), but it had to do with the resolution height. My laptop had 1440*900 and my external monitor needed to have the height lower then 900.
For further information, this is what the system profiler says about my graphics card:Display controller: Intel Corporation Mobile 945GM/GMS/GME, 943/940GML Express Integrated Graphics Controller.I hope you guys can help me, as plugging in a netbook to an external monitor (or TV) is not uncommon to me I like doing that, even if there's no point in it.I hope I gave enough information on this, I'm willing to give more if needed of course

I'm trying to add a higher resolution to my system. I've tried to edit xorg.conf but I think I'm wrong. Everytime I edit and reboot, it tells me I need to run in low graphics mode for now. Now I'm trying 'xrandr.' I was able to create a new mode just fine, but when I try to add it to the appropriate output, I get this:
Code:
prog@ubuntu:~$ xrandr --addmode LVDS1 1280x1024_50.00
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 149 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 25
Current serial number in output stream: 26
Here's what xrandr returns:
Code:
prog@ubuntu:~$ xrandr

I don't know why it puts it in TV1. There's two of them because I tried two different refresh rates.

After struggling with this for 2 days and getting nowhere, I found this simple solution.
1. Download packages http://ajoliveira.com/ajoliveira/gen...it_9.10.tar.gz and http://ajoliveira.com/ajoliveira/gen...rg.conf.tar.gz.
One of these contains the driver files and the other a xorg.conf file.
2. Extract the 2 archives by double-clicking on them.
3. Copy the xorg.conf file to the /etc/X11 directory code...

Just bought a new 1080p monitor (1920x1080) and it works fine in OpenSUSE 11.3. Problem is before I get the KDE start screen everything is not full screen. Now, I checked the rest of the forums and I cannot find a full list of widescreen or 16:9 grub resolutions.
Does anyone have a list of what's supported?

I lost the higher resolutions for my computer. The highest available is 1360x768 (which doesn't work well) and currently I'm using 1024x768. Before, I had 1280x1024 working well and I even had higher resolutions available in nvidia-settings. I've ubuntu 9.10 with nvidia drivers (185.18.36).
I've read [URL].. but not necessarily all of it or understood all of it. I've tried dpkg-reconfigure xserver-xorg and the xrandr stuff but nothing has changed, except what xrandr reports, regarding the addition of two modelines 1280x1024. In the end, I suppose something has corrupted some file but how can I figure it out?
Code:
Screen 0: minimum 320 x 240, current 1024 x 768, maximum 1280 x 1024
default connected 1024x768+0+0 0mm x 0mm
1024x768 50.0*
800x600 51.0 52.0 53.0
680x384 54.0 55.0

Just did a new install of 11.4 over top of my 11.3 and when I reboot into the OS it seems to boot just fine but the video is unreadable. When I boot into the failsafe the screen has a lot of gitter and the monitor tells me it's not in preferred mode of 1680x1050 at 60hz. All resolutions higher than 1280x1024 are unreadable. Tried booting nomodeset as I've read previous ... no luck. I'm still learning linux.

So I have been running uvesafb for a while now with no complaints, but klibc hasn't been updated for about a year. I contacted to the author and he said that he will have an update in the coming weeks. However today I was googeling around and to make a long story short, I have successfully been able to get a 1920x1200 console resolution with just the plain old vesafb. This is good news but I am also confused because I've been told many times that is not possible for vesafb to do higher/wide resolutions.

I have a Dell XPS M1330, which has a GeForce 8400M GS GPU. The binary (sigh) nVidia driver installed is version 190.53 (installed by sgfxi). This is working well: glxgears gives me about 2600 FPS and compiz is happy.An old Philips 170B is attached by VGA cable. I was looking to set up a method of switching resolution upon connecting to the monitor when working at the desk, since I don't like the 1280x800 resolution of the laptop.
nfortunately, I can't get any output on the external monitor. It does work under Ubuntu, which installed the 180 series binary driver. (Going to an earlier driver is an option, but I want to understand the problem.) Bottom line, I want to work under Debian.As far as I know, nVidia's proprietary driver doesn't support xrandr. At any rate, with he external 170B monitor attached and turned on, I get the following:$ xrandr -qScreen 0: minimum 320 x 175, current 1280 x 800, maximum 1280 x 800default connected 1280x800+0+0 0mm x 0mm
1280x800 50.0*
1024x768 51.0 52.0
960x540 53.0

after installing Natty on my brand new shuttle with Intel's Sandy Bridge Core i5 (2500K), everything works fine except setting up a higher resolution fitting to my screen.All I need is a 2048x1152 resolution, but all the display configuration in the hardware section of the system settings offers is 1024x768, 800x600, 848x480 or 640x480.The monitor is connected via VGA since it doesn't have a DVI or HDMI plug.Is there a way to tell the system there is more capability? Do I need a different driver? What and where can I check this?

I upgraded to jessie today and I am having problems with my background. When I log in, the background tries to start on the external monitor but then it fails to load. I can change the background in settings but it does not show up. The background just becomes black and I am not sure why.

I'm using the 270.41.19 nvidia properietary driver for my Geforce GTX460 graphics card. I have a Sony TV connected to my HDMI and I know it supports the 1920x1080 resolution. Yes it works after gnome or other DE loads up.
But during the GRUB screen and the bootup console - It defaulted to a 640x480 resolution (as it always does with the nvidia prop driver). I usually used to check the output of hwinfo --framebuffer and choose the resolution by appending the right vga=0xabc parameter.
But now I have a problem since hwinfo says the best widescreen 16:10 framebuffer resolution that my card supports is 1280x800. Here is the output from hwinfo --vbe which should give the info about both my gfx card and my TV.
The initial nouveau driver was able to output native 1920x1080 during the bootup on the console without issues, so I guess even the properietary driver should be able to output (If my understanding is right the nvidia module loads later during the bootup and only is required for the X but not for the console itself).

I have a problem with Plymouth. It works pretty well on low res, but on higher resolution some strange video artefacts appear - see attachments.
I use ATI proprietary drivers, if it has something to do with it.
The resolution is set in /etc/default/grub like this:
Code:
GRUB_GFXMODE=1024x768
GRUB_GFXPAYLOAD_LINUX=1024x768x32
edit: reducing colour depth doesn't help /end edit
I don't know whether it has anything to do with the current problem, but Plymouth used not to appear at all until I followed these instructions (or actually I took them from another thread but I can't find it at the moment and these are the same).
I don't know whether it's possible to take them during booting so I've taken these photos with a mobile and retouched in gimp to remove reflections (more or less), and since I'm no pro photographer nor photoshop/gimp master they look as they look. They should do to demonstrate the problem, though.

I'm currently using ubuntu 10.04 version. I've recently purchased a BenQ E2200HD monitor. However, the monitor is unable to configure a resolution higher than 800x600. I've tried changing it via 'preferences' - 'monitor' etc. The monitor model is 'unknown'. and the highest resolution available is the 800x600.
I've tried changing it manually, but it says x.cong file does not exist. Xrandr doesnt seem to work either. Or i would get CTRC 262. My current set up is, intel i5 2600, 4GB Ram, Nvidia GTS 240. I'm pretty certain, my graphics card (despite being in the low end) can support HD resolution. Even if it can't, it surely can support a resolution higher than 800x600.

I recently installed Debian, using the amd64 Network Install .iso. I'm using XFCE4 as my desktop environment, and everything is working well... on my laptop's screen.
My desired setup is to have my laptop sitting on a well-ventilated shelf, closed, and to have an external monitor be my main monitor. I want this because I'm using my laptop as my "home" computer, so it never moves, and I don't like the keyboard/trackpad. My laptop has a VGA output, and I can get my desired setup on my Windows partition (not stating a preference ; just that the hardware CAN do what I want it to).
I've been working my way around the Internet for a few days, now, and I've got the commercial NVIDIA driver installed. If I run sudo nvidia-config --twinview I can get my external monitor to be part of the display, which is great, but it's part of a dual-screen monitor setup, which is not what I want at all, because (a) XFCE's multiple virtual desktops are good enough for me and (b) my graphics card is integrated, and I'm trying to squeeze every drop of performance out of my laptop that I can (1 gig of RAM; the less that my graphics card eats into it, the better). Plus, it'd be annoying to accidentally drop something on my laptop's screen, and then have to dig it out of the shelf in order to undo it. I'm not saying that I'm consistently clumsy, but I'd eventually end up doing it.

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
[Code]....

I disabled KMS and checked for direct rendering with the glxinfo command. glxinfo, reported that direct rendering is enabled. This is good news, because it means that the i915 driver is being used.

Now, I need to write a custom xorg.conf file to force X to use the native resolutions of my chip.

I have two monitors of different resolutions. Under settings->display the settings for my monitor look like this: [URL]. Ultimately what I want is to set up this kind of configuration: [URL]. But whenever I do, it doesn't work out. When I up after setting the above settings, my configuration ends up like this: [URL]. Any attempt to change the resolution or to change the display type to anything other then clone is simply ignored. If I disable the second monitor I can set my first to the proper resolution. If I try to set the settings to what I want they will stick but the second monitor doesn't actually turn on, and if i try to drag windows that direction it acts like a single display.
I have tried using the ATI control panel to adjust my display, but there seems to be a problem entering it as an administrator.I can load the CCC just fine as a regular user, but when I try as an admin a terminal pops up, I type in my password, and nothing happens. I want to avoid trying to reinstall my display drivers or do anything drastic. In previous versions of linux I would just nano the Xorg.conf file and be done with it, but it seems ubuntu 10.04 LTS doesn't use Xorg, or at least not a Xorg.conf I am used to. I want to set the monitors at their native res and as independent displays, similar to what twin view did for me not to long ago.

I am somewhat new to CentOS, but I have read a lot of web pages and tried a good number of things trying to solve my own problem. I have made it worse a few times, but never better. I have an envision 1440x900 LCD monitor and a S3 Savage video chip on the motherboard. In System->Administration->Display->Hardware I am using generic LCD Panel 1440x900 and the video card is listed as "S3 Inc. VT8375 [ProSavage KM266/KL266]. I believe both of these to be correct. I have added the mode to my xorg.conf
The problem is, under System->Preferences->Screen Resolution, the mode 1440x900 does not appear. The highest resolution is 1280x768. Does the S3 Savage just not have the ability to produce 1440x900?

Today I bought a new monitor (IPS236V) to use it to watch movies and tv while I'm working on the other one.. I thought it's the best to activate Xinerama which could be done easy via CCC. But I'm not able to change the resolutions now as these panels are disabled in CCC. The first monitor is set to its native resolution, but the second is something lower.How can I configure both monitors to there native resolution?

first time poster after having read gobs of threads trying to find the answer to my issue here. I'll try to post as much information as I can, and then will supply whatever else is inevitably left out and deemed necessary. I'm running 10.10 on a Gateway MX3701 laptop which has an ATI Radeon Xpress 200M graphics controller (lspci | grep VGA) and am hooking it up to my Samsung P2770HD monitor/TV via VGA (VGA-0 port if that's important).
So, the issue: In resurrecting my old laptop by killing XP and putting on Ubuntu, I found I needed a VGA cable to connect to my monitor. Borrowed a friend's to get my setup going, and all was well in 1920x1080 with all the other monitor settings working well too (laptop monitor off, etc.. When my new VGA cable (cheap from Amazon) arrived and I shutdown, made new connection, and rebooted, my monitor was no longer recognized (it was before) and I am limited to weak sauce resolutions meant for my blinding grandmother.
So I've tried to find similar issues on here and have struggled to do so. I did find one thread that was similar, but the issue was never resolved.

I just installed Natty (11.04) on an old computer for my disabled brother with:
* Video Card:
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
* Monitor:
VGA Mitsubishi Diamond Pro 750SB (old CRT monitor)
The problem is that when I select System -> Preferences -> Monitors, the monitor is shown as unknown and it only allows me to set 1280x1024 (shows 0Hz as display refresh rate) which is way too high for my brother. I was wondering if there's a way to select the proper monitor from a list so all display resolutions are shown and I can select a lower one for him.

I have been tasked to set up 2 monitors on SUSE Linux Enterprise that are a clone of each other, but each displaying different resolutions. The primary display has a max resolution of 1024x768 while the secondary display has a max resolution of 800x600.
The problem comes when the secondary display shows a "cropped" version of the desktop. Is there anyway to show different resolutions on each display while maintaining the proper desktop look?

I am running Ubuntu 8.04 on a laptop. I have a 19" Acer monitor and in the past have successfully configured my xorg.conf to handle dual monitor setup with 1024x768 on the laptop and 1600x900 on the Acer monitor. What I have done now is run the laptop through a KVM switch. Due to this, I would like to set the Acer monitor as the primary monitor and just shut the laptop. How can I project my laptop screen to my Acer monitor so that I can use the 1600x900 resolution available rather than just cloning my laptop and using 1024x768?

The monitor on my laptop has become a bit sketchy and money is tight at the moment. I am currently connected to an Acer flat screen monitor. I have the ubuntu settings for using only the external monitor. This works fine once I"m in Ubuntu. Is there any way to force the display to the external monitor prior to ubuntu starting? This may or may not be a linux-related question. It was be very helpful if I could see my Grub menu on the external screen. I could not find any setting in my bios. The keyboard shortcut sometimes works but not on the grub menu.

I have an EeePC 1005HA with Intel 945G chipset and graphics. I've got a 21" no-name touchscreen attached to the laptop with the intention of hiding the laptop away behind it and simply using the tactile widescreen with virtual keyboard (onboard). By the way, the Touch screen is working great OOTB in Ub 11.04, although will have to tweak some more to get multi-touch working.On it's own the netbook runs 1024x600 (16:9) automatically. As soon as I plug in the larger monitor and mirror the images it auto-defaults both to 800x600 60hz and I have no options to select a higher res. I want to be able to run the large screen in something like 1024x600 or better, as long as its 16:9. At the moment everything is stretched out on the larger screen and on the netbook I have a 800x600 with black margins left & right.
Can't seem to work it out. The Monitor Config doesn't give me any higher options than 800x600 when mirrored. Below is the output of xrandr, if it's any help. Also my xorg.conf file is practically empty.

I just installed 11.3 in one of my computers and I've noticed the resolution was sometimes changing after a reboot. First it was switching from 1280x1025 to 1024x768 with the default deivers, then I thought installing Nvidia propietary drivers would solve the problem, but now is switching between 1280x1024 and 640x480. After several attemps to fix it I found out that the system uses the correct resolution if it starts with the monitor switched on, but falls back to 640x480 if it's off when the system boots, which is almost always since I usually control this pc trough vnc.
I Tryed to specify the available resolutions in xorg.conf, and adding the preferred mode option, but it didn't help. I tryed also to use xrand in .profile to force 1280 resolution, but it doesn't work either (when the system is started with monitor off, xrand only shows 640x480 and 320x240 as available resolutions, and so does the system preferences panel).
Here's the xorg.conf I'm using right now:
Code:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 256.35 (buildmeister@builder101) Wed Jun 16 19:25:59 PDT 2010
