Debian Configuration :: Samsung VGA Monitor With GT 730 - Can't Set Correct Resolution

Assuming this is the problem, does this mean I have to upgrade to Testing or install proprietary drivers?

Ubuntu Multimedia :: Changing The Screen Resolution In 9.10 Samsung Monitor

Jan 27, 2010

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.

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 30 - 75
VertRefresh56 - 61


With both 1600 x 1200 and 1680 x 1080 I get the resolution but I see lots of shadowing.(The letters are not crisp) Do I need to upgrade any driver ?

OpenSUSE Hardware :: 11.4 - How To Get Correct Monitor Resolution

Jul 8, 2011

I tested OpenSuse 11.4 as a guest OS via virtualbox on a win7 32bit host. Output to my 16:9 screen was perfect with a plentiful choice of high resolutions. Now with Suse (32 bit) properly installed as the host the only resolutions are 1024X768 and below and I am stuck with 4:3 ratio. My PC is an Intel Atom D945GCLF2 which has integral graphics. The monitor is the VGA input of a Samsung TV.

General :: Monitor Resolution Was Correct But Not Anymore

Jun 11, 2010

About three weeks ago I bought a new PC and installed Debian Squeeze. I have a Samsung SyncMaster 2494hs monitor connected to it. Until about an hour ago the monitor resolution was 1920x1080 and there were no problems. Anytime I clicked on system -> preferences -> monitors, the monitor preferences displayed the monitor name (Samsung whatever) as well as the resolution (1920x1080). An hour ago I did my normal daily upgrade via synaptic (synaptic -> mark all upgrades -> apply). When the upgrade were finished, the system indicated that a restart was required, so I restarted.

After the reboot, my monitor's resolution is set at 1152x864. System -> preferences -> monitors shows the monitor name as unknown and the max resolution available is 1360x768. Xrandr shows the max available resolution as 1360x1360, which is obviously wrong. According to discover I have an ATI graphics card. I've also run ddcprobebut that outputs about 15 lines and then stops with edidfail. I do not have an xorg.conf on my system or, if I do have one, it is not in /etc/X11.

Ubuntu Multimedia :: New Monitor - X Will Not Keep Correct Resolution On Restart

May 29, 2010

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.

Fedora Hardware :: Compaq W17Q Monitor - Correct Resolution Not Available

Feb 18, 2010

I have two displays: my main being an Apple Cinema Display (1920x1200), and my secondary being a Compaq W17q (1440x900). Previously all applications saw the secondary fine, being able to detect its name, native resolution, refresh rate, and so forth. But today, for no reason, after going into nvidia-settings the display is now being called "CRT-0" with only 4:3 resolutions available (1024x768 being the highest).

So now I'm stuck with the wrong resolution on my second monitor. All I can guess is that something more integral in Fedora is no longer able to read the EDID in it or something (I say integral as it's not just nvidia-settings, its everything, not to mention my install of Win 7 still reads the display A-OK)? Maybe I could just force the 1440x900 resolution? If so, how? Everything I've tried so far has either had no effect or resulted in glitch city.

Ubuntu Multimedia :: 10.04 Beta - Selecting Correct Resolution For Monitor

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.

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?

Debian Hardware :: Unable To Set Correct Resolution

Nov 1, 2010

I recently built a new computer and moved over my old graphics card, a nVidia GTX 275. Everything appeared to work fine, it booted with no drama etc.

I use my computer for work and gaming, all my work, web browsing, chat etc happens on Debian. I play games on Windows 7.I did a fresh Debian install on this box and everything went smoothly until starting xdm for the first time, it wouldn't go to a higher resolution than 640x480. I'd already installed the proprietary nVidia drivers and they appeared to be working fine, just at the wrong resolution.

Debian :: Jessie Can't Find Correct Screen Resolution

Jan 15, 2016

I'm using two screens where one Is cheep Denver TV screen with DVD player. I have just install Jessie on my PC. Before i had Windows and there was no problems finding correct resolution for this screen. Now Jessie recognize it as Unknown and the maximum resolution I can set is 1024x768 what is way to small even for this screen. At Windows resolution was something over 1200px wide. The worst thing about it is that this resolution stretches the display really ugly. You may think I'm making big deal of nothing but for me it is actually a deal. I'm graphical designer and I need to see display as it is.

Debian Installation :: Can't Set Screen Resolution / Get Correct Setting To Stick?

Feb 21, 2011

I installed Squeeze with LXDE on my old 600MHz Celeron, 256MB ram computer. But, every time I boot, the screen resolution is wrong. I can set it right with a few clicks of the mouse, but next time I boot up it has reverted to the wrong setting. I found that this problem has been reported on the LXDE forum, but the official response seems to be that it is not their problem.

How do I get the correct setting to stick?

Debian Multimedia :: Setting Correct Screen Resolution With Squeeze

Jun 18, 2011

I just set up my dad's pc with Debian Sqeeze. It runs perfectly fine and after trying a lot of distro's Debian is the only one that will not crash or freeze up X. Now we're forced to using my own 17" monitor instead of his 19" wide screen since the max res is 1280 x 1024 in Sqeeze. What he needs is 1360 x 768. I found out in the wiki that xorg.conf needs to be edited. Since the file does not exist it needs to be created by running "Xorg -configure" in tty after stopping GDM. when running the "Xorg -configure" command this is the output;

" vmware: Please ignore above "FATAL: Module vmwgfx bot found."
(++) Using config file: "/root/"
(==) Using system config directory "/usr/share/X11/xorg.conf.d"
Number of created screens does not match number of detected devices.
Configuration failed. "

It's an Intel Sandy Bridge integrated graphics chip. I've tried running "Xorg:1 -configure" as mentioned in a forum but that simply gives me a "unknown command" answer.

Debian Configuration :: Correct Way To Start Multiple Instances Of MPD?

Mar 18, 2010

The first thing that comes to my mind is to add (copy) the script in /etc/init.d and the /etc/rc* directories by hand. Debian's automatic handling of init scripts on package install/removal is quite nice, so I tend to shy away from making any manual changes if there's an automated way to do it. Which leads me to the question: is there an official way to run a second instance of a daemon? (Tried google, didn't find much more than a bug report).

Debian Hardware :: Monitor AOC F19s Not Operating At Optimal Resolution?

May 30, 2011

This is a fresh install of stable Debian: root@ngaio:/home/murray# uname -a Linux ngaio 2.6.32-5-amd64 #1 SMP Wed May 18 23:13:22 UTC 2011 x86_64 GNU/Linux The monitor is an AOC F19s - fairly standard 19" widescreen LCD. The graphics is running off the mother board: Intel Graphics Media Accelerator X4500 (supposedly this supports up to 2048x1536)

Gnome has three basic resolutions available, the best is 1024x768 but it still makes my pictures look fat. The optimal resolution for my monitor is 1366x768 (ie widescreen). I have hunted through lots of posts and tried creating an xorg.conf file and specifying this mode, however when I did that the Xserver simply didn't start. I then tried a few different combinations, however I was pretty much swatting mozzies with the lights off. I deleted my xorg.conf attempt and it's back to 1024x768 and I'm stumped.


I know these resolutions are painful to work out, so if you don't have much time perhaps you could point me at a website or document that explains how to configure xorg.conf correctly?

Debian Configuration :: Low Resolution Graphics

Jun 24, 2015

I installed a GIMP plugin (David's batch processor gimp) and a lot of packages got updated in the process.

The monitor resolution dropped significantly and going to applications -> system tools -> preferences -> settings -> display gives me the message 'could not get screen information' my webcam and microphone is not recognized anymore either ALT + TAB does not change between open windows. power off does not work. I have to shutdown the system using the command line.

The GUI has changed a lot as well. new color schemes (that I don't really like) file system manager has a completely new look too.

it is very strange. My GRUB screen is still in the old resolution. when the system boots up at some point the resolution changes to the lower resolution.

I'll be posting a photo later on today to show you people exactly what I mean. So that I can have Ubuntu's screen would fit all inside my LCD screen ? The HTPC runs an nVidia graphics card.

Debian Configuration :: Host Name Resolution Failure?

Aug 15, 2011

I am experimenting with installing a bare minimum, network capable installation of Debian Squeeze. Right now, I am having trouble getting proper host name resolution. I have provided the output of ping (which is able to resolve names), wget (which is unable to resolve names), and the contents of the files I believe to be relevant to the problem. When I installed Debian, I installed *only* the SSH Server from the list of available configurations. Since then, I have installed mdns4, dnsmasq, mdns-scan, and libnss-mdns to get name resolution to work with no success so far. All packages were installed with no recommends -- aptitude -R package name. What am I missing to get host name resolution working?

Ubuntu :: 10.10 Does Not Use Correct Resolution

Apr 4, 2011

I recently set up Kubuntu for my parents, and its working fine, other than the screen resolution. When I log in, it uses 800x600 when it should be using 1280x1024. I've tried to generate/ edit xorg.conf, but Kubuntu doesn't seem to pay attention to it. Also, I don't know if it matters, but it seems to be detecting a second screen that doesn't exist (see picture). That "monitor" can only go up to 800x600, but when I disabled it, it stayed off. When it was on and I pressed identify monitors, however, it put both labels on the main monitor. Here's the picture of the two monitors:

Debian Configuration :: Nouveau: Resolution Re-ducted To 1024x768?

Oct 28, 2010

Motherboard: M2N-MX with Athlon X2 3600 from 2006 onwards
00:0d.0 VGA compatible controller: nVidia Corporation C61 [GeForce 6150SE nForce 430] (rev a2)
Kernel: Debian Sid with 2.6.32-5-amd64 and custom 2.6.36-rc7
Monitor: Samsung 712N, 17inch, with native 1280x1024 resolution

Everything was fine with both kernels with custom 1280x1024 resolution upto yesterday. But when I rebooted today, first I noticed that X stopped working. After updating xorg.conf to 1024x768, it started working . After going through the kernel log in /var/log/messages, I noticed the following differences

Yesterdays log:

nouveau 0000:00:0d.0: Detected 64MiB VRAM
nouveau 0000:00:0d.0: 64 MiB GART (aperture)
nouveau 0000:00:0d.0: Saving VGA fonts


There is an extra "Load detected" line and the resolution got reduced from 1280x1024 to 1024x768.

Debian Configuration :: Xorg Affects Console Resolution?

Nov 2, 2010

I've been scouring the internet for an answer to this problem. I am using Squeeze and have properly configured Grub2 to set my console screen resolution to 1024x768x32 (as per updating /etc/default/grub to contain 'GRUB_GFXMODE=1024x768x32' and updating /etc/grub.d/00_header to contain 'set gfxpayload=keep') and everything works wonderfully. My resolution is set as it should be. However upon installing Xorg (aptitude install xorg ratpoison), my console resolution gets changed to what appears to be 1280x1024.

I thought that this was due to xrandr, however when I issue:

# xrandr -s 1024x768

only the X resolution is changed. When I then CTRL-ALT-F1 back to the console, the resolution is still at 1280x1024 (I am aware that xrandr only affects X, but I assumed that because my console resolution was correct before installing X there might have been some correlation).

I would like for my console resolution to stay at 1024x768 as per Grub2's configuration and for X's resolution to be at 1280x1024.

PS I also noticed that prior to installing Xorg, my CPU boots up without any screen blanking (only for a second or so). However, after installing Xorg, during the boot process the screen does blank briefly. It is at that time that the resolution gets changed to the 1280x1024 setting.
