Fedora :: Screen Resolution With External Monitor?
Aug 28, 2009
I installed FC11 on my laptop T43 and the video card is ATI Mobility Radeon x300. Now I have a problem of screen resolution with external monitor:
When I do presentation, I have to mirror the two monitors and both set to 1024*768, which is not perfect.
I remember that when I use RHEL 5 desktop edition, The system can automatically detect the external monitor and set it by itself ----- The laptop uses 1400*1050 and the external monitors such as projector uses 1024*768. But I haven't found such feature on FC11.
I have Ubuntu (running Jolicloud) on my HP dv2000 laptop, connected to my Sony AV Receiver through HDMI to use the TV as an external monitor. However, the resolution seems to be slightly off as the outer edges of the screen are cut off. Is there a way to fix this by editing the xorg.conf file? My current setup is below. I tried adding the line "Virtual 1244 700" to the subsection "display", but when I restarted it threw me into low graphics mode. Is there anything else I can try?
I also tried setting up the resolution at 1920x1080 on the TV and kept the default resolution on the monitor as 1280x800, and as you would expect displays the entire desktop in a smaller version on part of the tv. However, the desktop is still offset, leaving the top and left margins cut off. So, perhaps I need a way to offset the screen? Is this possible in xorg.conf?
I am having problems getting my external monitor to work. When I plug in the monitor, both the laptop screen and the external monitor go black. When I unplug the monitor, the laptop screen works again. When I startup with the external monitor plugged in, neither screen works or teh computer hangs or something.
I have had the external monitor going on a couple of occasions. I did manage to configure my monitors through System Settings > Display. I turned off the laptop monitor as I just want to use the external. But after rebooting, things didn't work.
OS: Fedora 12 Video card: ATI Radeon 9200 series Monitor: ViewSonic 19"
I installed Fedora 12 configured Gnome automatically. Generally default settings. My monitor was connected directly to the video card and all was good. My video card was detected and my monitor was detected as ViewSonic Corporation 19" and I can set the screen resolution to 1280x1024. I had no xorg.conf file, as it seems that Fedora 12 does a great job of PnP to just set everything up.Now I go and complicate things by hooking up my monitor through a KVM switch. All of a sudden my monitor is "Unknown" and the best resolution I can achieve is 800x600.
Sure, I could go and reconnect without the KVM, but I want to be able use it.Is it possible to edit xorg.conf to tell it "Trust me, just use 1280x1024 at 60Hz even though you can't figure out what the monitor is"?
I tried a number of the posted suggestions to generate xorg.conf files but none of them get me what I need. A simple sample file listing that does the minimum is greatly appreciated (I can experiment from there once I get a basic setup working).And can someone explain if it is X or the ATI driver that is getting confused by the unknown monitor type. It helps to know what is actually going on in addition to a fix (so I can figure it out myself in the future). Thanks!
First off, let me say: I'm a long time Linux hobbyist and recently installed Fedora 12. I've been looking (some say "lurking") around these forums for a bit after I loaded it up and let me say: Leigh, You're an amazing young man! Keep up the great work! I've a question: I've just put together a hobby computer: Pentuim 4, with 1 Gig of RAM and a Nvidia Geforce5700LE. When I install Fedora from a fresh install, everything works great: nice screen resolution, good graphics, etc. but no 3d or acceleration, so I'm very limited on my programs.
So I decided I need to upgrade my Nvidia driver. I followed Leigh's Nvidia setup guide after installing Fedora 12 (all four steps!) everything seemed to go fine, but when I reboot, I quickly see the Nvidia splash screen, but the screen then goes blank. Well, not really blank, I can see what appears to be a kind of cross-hatch pattern, plus I can see what should be my mouse cursor on screen (it also is a square shaped pattern). I suspect it may be at a screen resolution that my monitor doesn't support. Once there, the computer pretty much doesn't do anything else. Usually I can break into the x driver loading and go to the command prompt, but this latest time I can't even do that.
after upgrading from 10.10 to 11.04 i received the Unity as a default. with the help of this forum i figured out how to get the Gnome.i would like to try the Unity but when i am switching to Unity i cant get the resolution i need to my external monitor.i have an application, Switch resolution that doesn't work under the Unity but does work under Gnome.i can change the resolution in the external monitor to its native resolution but than i get the upper panel in a good resolution and below only black without any window or anything.
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'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 have finally decided to reach out for help because I've been messing around for 3 days with xorg.conf and I'm a beginner and not getting it right. What I want to do is to use only my external monitor (1920x1200) via DisplayPort when my computer is docked. And then my laptop display (1280x800) when undocked. I am using Ubuntu 10.04.
I have setup System->Preference->Monitor: Unchecked <same image in all monitors>, turned off laptop display, and set External monitor to 1920x1200. After doing this everything works when in Xwindows. The resolution is correct when I am docked, and when I am undocked it defaults to my laptop display.
The ONLY problem with using the System->Preferences->Monitor is that when I start up the computer when docked the external monitor goes to the incorrect (laptop screen) resolution at the initial login screen. After I login the resolution corrects itself but it's messy with reinitialization of the screen and my icons being all messed up. I think this happens because these settings only take effect after logging in.
I believe I have to edit the xorg.conf to get my setup working at the login screen. Can someone please tell me how to this.
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

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.
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?
so when ppl bring me their computer and i install them ubuntu in my monitor when they take their computer to their home ubuntu does not keep the screen resolution i set for them.
I have a old Pentium III box with equally old monitor (It says LG Sutdioworks 45v).I have installed Ubuntu 10.04 LTS.I have found it difficult to setup my screen resolution. It shows by default 800x600.After some tweaking I can stretch upto 832x624.I have seen resolution up to 1024x768 in windows on the same box and same monitor.How can I improve the resolution?I have searched and found out that i need a xorg.conf setup as Ubuntu cant identify my monitor properly.I also installed ddcprobe, read-edid.However I have met with limited success.
I am new to Linux (Ubuntu 10.4 LTS on a Thinkpad T40), now just two days, and had everything working nicely. But since I wanted a better higher resolution I tried to set the monitor resolution to a higher value. After selecting a higher resolution first the screen went black and now it has a white background and is steady but has flickering areas. The system is still working. How can I go back to the resolution that was working?
I changed may graphic card, earlier I used NVIDIA FX5500 with nvidia driver, now I was trying to use ATI Radeon 7500, but there are problems with graphic configuration. At first attempt server started but after I changed a screen resolution the monitor went blank. I restarted a computer but after the X server started immediately the monitor wnet blank. I found that for completely for me unknown reasons Xorg was trying to use an NVIDIA glx module with radeon driver. I removed this nvidia driver, I expected ubuntu would be able automatically to set up a proper configuration, but instead of ubuntu complained about a missing driver. I also tried manually to set up some basic config using Xorg -configure but after that the Xorg server was stuck.
I have an external monitor connected to my laptop (extended display). I always drag the Totem player from the laptop screen to external monitor to watch video files. I wonder, if the Totem player can be set to open in the external monitor automatically, everytime I open it?
My software and hardware information are as follows. I have Fedora 12 and KDE 4.4.5 installed on a Dell Vostro 1500 laptop. I believe it's a 64 bit processor; it's an Intel Core 2 Duo CPU. The external monitor is a Dell as well.
My problem is that my system does not seem to be detecting an external monitor that I have connected. Everything else is working just fine; however, I would like to have the option of attaching an external monitor. When I plug the external monitor into the laptop, the external monitor remains black and appears to be in power save mode. The results of xrandr -q (with or without the external monitor attached: it doesn't appear to change) are as follows.
Code:
How can I get my laptop to recognize that the external monitor is even connected? Let me know if I can be more specific or provide additional details.
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 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'm using Xorg 7.5 on a Radeon HD4870 with the FOSS radeonhd server on my HP 6830s. The laptop has a VGA connector and I attach it to a 37" panasonic plasma TV. It works fine except for a little annoyance: when activated, the TV screen is set to the resolution of 1360x768 (which it reports as being the highest it supports) but all the image is shifted by about 100 pixels to the right. I can't see the leftmost part of the page, and I have a black vertical bar to the right.
If I change the resolution to 1024x768 there is no shifting, the image fills the entire screen with no parts hidden, but at this resolution the image is stretched. How can I tune the position on the external monitor so that the image is centered in the screen filling it entirely?
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 laptop is a samsung X30 and i spent days trying to install ubuntu 10.04 unsuccesfully as there was no clear picture on the screen, just a black and purple splodge. I then saw a post on these forums discussing the default resolution of ubuntu and how it is incompatible with some machines so via VGA cable i connected it to my TV and sure enough i could see what was going on and finished the installation process. I assumed that once ubuntu was fully installed i would be able to change the resolution using the monitor preferences but none of them worked. I am now faced with the problem that unless plugged into the TV i have no picture on my laptop, does anyone know why my laptop screen wont work with ubuntu and how
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.

on a 6-7 years old compaq laptop, connected to a brand new hp monitor i am having a mismatch with computer/monitor resolution.
before i had ubuntu 10.04 which could only run in x's safe graphics mode - allowing for full screen resolution but with handicapped graphics - for example videos fullscreen would be quirky and run with cpu at 100%, something which was no problem before 10.04.
then i tried ubuntu 10.10 and later lubuntu 10.10 (which had exactly the same problem); the monitor is running 1440x900 while the computer is rendering to only 1024x768 - leaving a huge black border on right and bottom of screen. the gfx is still crippled; videos fullscreen is quirky as before.
I am running Debian 8.3, and I'm running Gnome 3.14.1.I have an external monitor plugged in with HDMI, and while Linux is loading both screens are on duplicate. Once the GUI kicks in, only the external screen works, so I have to enter my password blindly. Then, I open a terminal and run
I'm a new user and recently installed ubuntu on an old samsung laptop, during the installation process i couldnt see anything on the screen and came to the conclusion that ubuntu's default resolution was different to that of the laptop screen so i plugged it into my TV and sure enough it worked however i still only have a picture on the tv, ive tried all the resolutions available in the 'monitors' box but nothing, does anyone know how to fix this?
I have an HP Pavilion dv9000 which I would like to use completely with any Linux OS. I have tried to install Linux Ubuntu 10.04.1 but it appears that it doesn't recognize the external monitor and ends the installation. I have a clean hard drive that I could install but I do not know which of the two drives I should replace. I can only get into windows in safe mode and I would think this may have something to do with the problem, don't no.
I recently purchased a cheap computer to use for everyday tasks. It came pre-loaded with Windows 7. The monitor I am using is a Vizio VX20L. It's native resolution is 1366X768. I have no problem with the screen resolution in Windows 7 but in Ubuntu, I am having some issues. I have the propriatary Nvidia driver installed in Ubuntu but for some reason I cannot get the screen resolution right. I am currently using a resolution of 1360x768 and the right part of my desktop is not on the screen.
I have tried to adjust the screen size using the monitor settings, but I still cannot get the whole screen to show up. If I set the resolution to Auto in the NVIDIA X Server Settings, it defaults to 1280X1024 and I can see my whole desktop, but it is streeeeetched. Here is some relevant information pertaining to my system:
I'm using Ubuntu 10.04 Integrated Video chip is NVIDIA GeForce 6150SE The driver I'm using is NVIDIA accelerated graphic driver (version current)[Recommended] screen is a Vizio VX20LHD
