Ubuntu Multimedia :: Monitor Won't Detect Proper Resolution / Solve This?
Dec 27, 2010
This has been happening with the majority of screens I try to plug into, but the proprietary nvidia driver never detects the correct resolutions -__- the open-source driver works perfectly with a little xrandr magic, but I'd like to have some 3D acceleration going on. I'm using the desktop version of Nvidia ION and ubuntu 10.10, with the current nvidia driver (from the repositories). The native resolution is 1440x900 @60 Hz. Any thoughts on this? Again, the nouveau driver is great but I'd like to have VDPAU and the like working. code...

My monitor is the hp pavilion f1703. The 9.10 only offers 2 resolutions 800 x 600 (4:3) and 640 x 480 (4:3)The native screen resolution is 1280 x 1024 @ 60Hz which is obviously not offered. I did my homework and followed this guide found here http://www.ubuntugeek.com/how-to-adj...on-ubuntu.htmlall i got was 'xrandr:cannot find mode 1280x1024' when i try to set the resolution manuallyThe weird thing is ubuntu 8.10 detects my monitor native screen resolution just fine.

It seems that whenever I boot my laptop (hp probook 6450b) without a monitor attached, then boot with a monitor later attached, the configuration gets all messed up.
Currently, if I boot with the monitor attached, right after the blue loading screen (at the login prompt) i get two black monitors and a mouse, with no login screen. Unplugging the monitor shows the login screen on the laptop.
If i boot without the monitor attached, log in, then plug it in, i see the following from xrandr:
Code:
Screen 0: minimum 320 x 200, current 2390 x 768, maximum 8192 x 8192
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 310mm x 174mm
1366x768 59.6*+
1024x768 60.0
[Code]....
However, now when I reboot, all settings are lost, and if the monitor is attached, i get the black screen with a mouse at login.
I did notice that when I shutdown, it hangs on "Running guests on default URI", and i get a stack trace. It will keep dumping stack traces, and i have to hold down the power button to force it off.

I am having video issue with ubuntu 9.10 and centos 5.4 cannot get resolution higher than 800x600 on Viewsonic vg930m monitor...The first time I installed ubuntu 9.10 worked great, since then no better than 800x600 on both linux distros. Any ideas it is very annoying, like using web browser on a small tablet pc....This monitor works great with opensolaris, though.
Using both distros in virtualbox right now but even if not virtualized install on hard drive I cannot get higher than 800x600...Driving me nuts.

I've installed Squeeze 2.6.32-5-amd64 on my laptop (Alienware M17X R3, Intel i7 Sandybridge, ATI Technologies Inc Broadway [ATI Mobility Radeon HD 6800 Series])The screen is 17", with maximum resolution of 1920 x 1080. After a default install of the operating system, the maximum resolution I can select is 1280 x 1024.My research so far has suggested that I need to edit the /etc/X11/xorg.conf file and provide xorg with the necessary resolution.
Again, by default, the xorg.conf file is not created. This leads me to believe that xorg is scanning my hardware at startup and providing me with whatever it thinks is appropriate. I tried following these instructions to generate an xorg.conf file. This process created an xorg.conf file under /root/.
When I copy this xorg.conf file to /etc/X11, I get a blank (i.e. black) screen. Deleting this file restores the default resolution 1280 x 1024.This system is dual booting with Windows 7. Under windows I am able to get a 1920 x 1080 resolution, so I know my hardware is up to it.At this stage I have yet to install the drivers for the Radeon graphics card.What are my options regarding configuring xorg to give me a higher screen resolution?

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 have a LMDE (Mint Linux Edition based on testing, now Wheezy) i386 that I just did a dist-upgrade on and now it isn't properly detecting my monitor resolution. I have two 1680x1050 monitors, one attached to the DVI and another to a VGA video switch. When I rebooted to the new 2.6.38-2-686 kernel both monitors were giving me 1024x768. I futzed around for a while and could then get the the DVI monitor to correctly identify the proper resolution, but the VGA monitor resolutely refused to see more than 1024x768.
I was able to get the proper resolution by entering these commands:
[Code]...
Should I file a bug report, and if so, with whom? I have to say, the Debian bug report process is not too newbie (or even not-so-newbie) friendly, but I'd like to help if it doesn't require me to hand-configure a MUA.
Also, I suppose I shouldn't mention it in a single post, but my mouse is behaving rather unpredictably now (click speed, selecting), and trying to reboot dismounts the file system and then starts up again giving me my display manager (in my case KDM), without restarting the system (both from "sudo reboot" and trying to restart with KDM or the Gnome widget). If I really want to restart the system I have to halt it first and hit the power button.

Ubuntu 8.04 used to detect my display resolutions fine, but this version is unable to detect my max. resolution and I get lock-ups when I use the live disk without the "nomodeset" option.
My display config is:
lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)
Detected resolutions (with nomodeset option):

VGA connected 1024x768+0+0 (normal left inverted right x axis y axis) 267mm x 200mm
800x600 85.1 + 85.1 72.2 75.0 60.3 56.2

720x400 85.0 70.1
640x400 85.1
640x350 85.1
The resolution 1152x864 is missed. This was a bug I had earlier reported on Intrepid (9.04).
My OS:

I downloaded this 2 days ago. Also I was stumped at no kernel messages on any virtual terminal! How can I enable the printks?

I'm running 10.04 on a Radeon HD 4650 card with fglrx. The driver installation went without a hitch, and the log file contained no errors.
When I try to run
Code:
aticonfig --initial
i get the response
Code:
Found fglrx primary device section
Unable to find any supported Screen sections
Running
[Code]....
My best guess is that I have to write an Xorg.conf file, in which I say what type of monitor I have.
I cannot do that, as I need to shut down the Xserver in order to make it generate my xorg.conf file. When I shut it down I get the black screen.

I occasionally connect my laptop to my TV and watch shows on the larger screen.After upgrading to 11.04, "Detect Monitors" no longer detects my TV. This worked in 10.10 and 10.04, and possibly in earlier versions.

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 have a 30" apple cinema display. The monitor handles up to 2560 x 1600 pixels which is the optimum resolution for this monitor. I found out that most apple monitors have nvidia graphic card.The monitor is hooked up to a motherboard Intel BOXDG45FC. This motherboard has Onboard Video Chipset Intel GMA 4500. However, using KDE interface I dont get beyond 1280x800 resolution for the monitor.How can I get the maximum resolution for the monitor?

I just switched monitors to a Viewsonic VX2025 and I am unable to get beyond 1280 x 1024 using the nvidia x server settings. My graphics card is a GeForce 5200. These are connected with a DVI plug. I would like to be able to set my resolution to 1920 x 1080. (Also, the card and monitor worked at 1920 x 1080 in a previous windows machine.)
I have done a fair bit of searching and it appears that my issue is either the x configuration file or EDID. After 2 days of working with this it's gotten confusing to say the least. So, I'm looking to see if others have had a similar problem and how to solve it. I have not altered an x config file before, so not exactly sure of where to begin.

i'm trying to set the resolution to 1440 x 900 on ubuntu manually since it's not being showed under the options. I've followed this tutorial [URL] The problem is that i don't have the output name to add on this command (as you can see below under the xrandr command.:

Since a fresh install of lynx, I've been having problems trying to get my resolution of 1366x768 to fit properly onto my monitor, regardless of what I try, the screen does not fit completely inside the monitor, and I have to pan around to view the entire desktop.
I haven't had problems with this in previous versions of ubuntu. I've tried all the nvidia driver versions in the repository, as well as the latest from nvidia itself and they all do the same thing.

I've just bought a new monitor - Viewsonic VA2213w and am trying to set it up with Lucid. The resolution required is 1920x1080 @ 60Hz. I have an NVidia GTS250 with the proprietary driver v195.36.24 installed. I can set the right resolution in the nvidia-settings app, but it will not survive a restart. X always reverts to 1024x768. I have manually edited xorg.conf now to try to force the mode. The GDM login screen displays at the correct resolution, but on logging in X changes the resolution. Xorg.0.log shows the resolution being correctly set to 1920x1080 initially, then right at the end for some reason it is reset to 1024x768.

I have two video outs on my AGP video card. One is VGA and the other is S-video. I tried connecting the second monitor (Viewsonic) by itself to the VGA port and it works fine and runs at 1280x768 very clearly. I then attached the LG monitor instead to the VGA and attached the Viewsonic to the S-video port. Now it is running at 1024x768 and I have no option to increase the resolution.Is this a limitation based on S-video being worse than component, which is worse than VGA and it simply cannot handle the data density for larger resolutions? Or would it be my video adapter? I swear I had monitor control working fine through the panel, but now when I click on the monitor button it says, "It appears that your graphics driver does not support the necessary extensions to use this tool. Do you want to use your graphics driver vendor's tool instead?" and that opens an Nvidia X control panel.
Also, using S-video means the computer doesn't recognize the Viewsonic LCD TV properly, it just recognizes it as a TV. Is this because S-video doesn't play nicely with EDID reporting?It would be nice to get a sharp picture on that TV, the way I had when it was connected like a monitor via VGA. I am not sure what's going on anymore, so any help on clearing up driver issues or getting configuration apps installed or anything like that would be helpful.

I started using Ubuntu 11.04 today.
Everything works fine with my monitor directly connected to the computer. I get a default screen resoluton of 1600 x 1280, which is just fine.
However, when I connect the screen through a video splitter to be able to use a beamer, the screen resolution defaults to 1024x768. Moreover, Ubuntu then detects an unknown monitor.
I recall that I have solved this problem before with an older version of Ubuntu.
Now it seems that there is no xorg.conf anymore so I don't know what to do.
How can I force Ubuntu 11.04 to start with a screen resololution of 1600 x 1280.

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.

Got a system that I've been using for a long time now without any problems. Now suddenly it won't use a higher resolution than 1024x768.I never added any mods to the configuration and have not added any software other than recommended updates it quite a while.Any ideas what happened or how to fix it? I checked and the monitor/graphics card will still do upper resolutions with windoze so I'm guessing the hardware is alright.Using OpenSuse 11.3, 64bit, on a dual core athalon with a Sapphire ATI x1600 graphics card and a 22 inch flat screen that is supposed to go 1600 x 1050.

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 am running Ubuntu 9.10 on a new HP PC (Pavilion p6240f PC).This came with an Intel GMX X4500 Integrated graphics.My monitor is Samsung SyncMaster 2333. Initially I got a very bad resolution, Later I edited /etc/X11/xorg.conf (created the file) and added the following.

I recently got a computer and installed the ubuntu 10.04 beta on it. I'm having issues getting my monitor to display at the correct resolution. It should be displaying at 1440x900, but the highest resolution I can select from the displays configuration panel is 1366x768, which is not even the correct aspect ratio.

This is the whole thing, in case it helps.
From what I have read, this is a brand new chipset with the GPU built into the main CPU, as if it were another CPU core. Is there a driver for this yet, or do I have to deal with an improper resolution?

I'm using a laptop and running a secondary monitor to my TV. My laptop has ATI HD 3400 video card. The TV has a higher resolution than the laptop's monitor. When the video is full screened on the TV, the actual video uses the resolution of the primary monitor and not the second.

I have a dell studio hybrid PC which I am hooking up to my TCL brand 40" LCD TV to use as a media center pc. The problem I am having is that I can't get the TV's native 1920x1080 resolution to display properly. The rendered desktop doesn't quite fit in the screen (I think its the top and bottom edges that are cut off) so for example the menu bar at the top is completely off the screen.
1680x1050 works fine in the sense that it fits the full desktop to the screen size, but its not the native res. In the resolution changer utility, it recognizes that my TV is a TCL brand but mentions 36 in the model name (the TV I have has 40 in the model name to denote 40") so I think Ubuntu is recognizing the wrong size TV. How can I finagle the screen settings to make the 1920x1080 fit properly on my monitor? Or get Ubuntu to correctly recognize my TV? My TV is a no-name brand so its hard to find info on it or others setting up linux with it.

I have problem with resolution (@gnom desktop). In Yast --> videocard & monitor is all right. There is correct resolution 1366x768 (WXGA). Also the videocard ( I don't have really one, only chipset "Intel Mobile GM45" ) is correct recognized. But Monitor isn't recognized, and I don't know which one I have (It's notebook from acer).
Nevertheless if I go direct in monitor preferences (at the bottom the monitor with a ruler symbol) the resolution is set to 800x600 and I can only change to 640x480. The monitor is as 15" recognized (I have 15.4", even a bit more broadly - 1366x768) and now I don't know what to do. All symbols, all programs, everything is huge! How is it possible to configure the correct one resolution?

I actually do have a GeForce4 MX 460 in this pc. I have a 7950gt in a different pc. Oops. I guess the MX 460 cant do 1600x1200 on the dvi output but somehow it can do it on the vga output? I guess I could just use a vga connection instead of the dvi connection.
The problem I'm having is that my LCD monitor (acer AL2021) can't be used at it's native resolution of 1600x1200. This is probably because my GeForce 7950gt graphics card is not being recognized. Xorg seems to think my card is a GeForce4 M 460. (It's not, really!) I'm using Ubuntu 10.04 LTS.
Here's what I've been doing for the last few hours:
This didn't work. 1600x1200 is still not listed.

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

I installed 9.10 on a computer I'm working on, and right away the graphics went out. It won't display the proper resolution without shoving the display significantly to the left.
After MUCH Googling, I found that this can be fixed by a driver called i915. After much MORE Googling, I found [URL], which as you can imagine filled me with relief.
And THEN I try to follow the instructions and discover to my pure horror that GRUB has been gutted and made unusable in 9.10. GRUB2 just simply does not seem to have an option to insert the i915 driver into my boot command.
should I just forget this unstable release and burn a 9.04 disk instead?
