General :: X-Window Modeline For High Resolution Modes On NEC LCD 22WV Monitor?
Apr 30, 2010
What should look like X Window System (X.Org) modeline to be put in xorg.conf, for high resolution (incuding recommended 1680x1050 @ 50Hz resolution) for 22" NEC LCD 22WV monitor? X.Org autodetect correctly only 800x600 and lower resolution SVGA modes,unfortunately.1,2
How can I generate proper "Modeline" line for xorg.conf? Is information included in NEC_Datasheet_LCD22WV-english.pdf enough (found on NEC LCD 22WV product info page)? What tools there are available to generate proper modeline for a LCD monitor for Linux? MS Windows (MS Windows XP Home) correctly detects and use 1680x1050 resolution; can I somehow get modeline information from MS Windows?
Footnotes:
1) It might be hardware problem with the monitor itself, as the same LiveCD Linux distribution that couldn't autodetect recommended 1680x1050 mode for NEC LCD 22WV monitor, correctly autodetects recommended 1440x900 mode for slightly smaller NEC LCD 19WV monitor from the same family, by the same producent.
2) Or it might be problem with graphics card (NVIDIA Riva TNT2 M64) not supporting such resolution, or with graphics driver not supporting such resolution.

I have a dell latitude with intel i7 nvidia NVS 3100M and screen 1920x1080 resolution, using KDE 4.4 stable suse, well with high resolution monitor I found some problem usng kde:
1- I can change the font dimension by system settings but if I bigger the font the dimension of Kmunu doesn't change so the result is big font in small container, ugly and difficult to use
2- I can change the font dimensions in KDM splashscreen but the window where username and password is shown doesn't change, result is big unreadeable font in a small case
3- I cannot change the tabs and theyr font dimensions in chromium and firefox, result very small tabs
4- Icons in system tray and Kmenu and other icons remains always small even if I bigger the panel

I have a problem with my screen resolution in Linux. This happens with both openSUSE 11.4 and Fedora 15. The moment my PC restarts after I have installed the operating system it will boot up with a screen resolution higher than my monitor supports. My screen supports a maximum resolution of 1600 x 1200 @ 75Hz and Linux sets the default resolution way too high at boot, now all I get is a message from my screen asking me very nicely to change the signal timings, but I can't because I can't see anything to change it to a lower value (I don't want it so high anyways because then everything is too **** small). My monitor is a SONY GDM-5410 and the Graphics card is an AMD Radeon HD 4870 1GB. It nly works when I boot the system to FailSafe mode, but then I can't cahnge it permanently.

I want to use 1920x1080 in the virtual consoles, with:
Debian Squeeze; proprierary ATI drivers.
Switching back to the open source drivers, it works automatically, but I got no clue with these ones. Someone say I should use uvesafb by modifing initramfs accordingly.

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.

I am using Ubuntu 10.04 and had the dual monitors all set up using NVidia. When I was leaving my office I intended to lock my screen but instead switched to guest user . . . and now 1 of my monitors from my dual monitor set up has bunk resolution?
I have restarted and am logged in as administrator but I have no idea how to fix the resolution? The dual monitors have always been a problem for me. what in the x11/xorg.conf file I need to change?

My screen resolution is only 640x480 after I installed the nVidia driver by authority method of 1-click install.
And then I run nvidia-xconfig,/etc/X11/xorg.conf was built.Restart my PC.
I selected the default mode to run opensuse.My screen was black.
So I select the failsafe mode and remove the /etc/X11/xorg.conf.
I try to copy my ubuntu 10.3 /etc/X11/xorg.conf,but I failed,the screen was black when booting default mode.
Now my LCD resolution is so low.
Graphics card:nVidia Geforce 5200
Monitor:19 inch widescreen LCD
And I can keep the best LCD resolution 1440x900@60Hz in the Windows XP successfully.

I'm running Kubuntu 9.1 (KDE 4.4) on an IBM Thinkpad T30. By default K set my resolution to the highest output of my graphics card (ATI Mobility Radeon 7500) which I was able to change via xrandr at command line, however now the K menus and taskbar appear to be set at too high a resolution of their own to properly display. The K menu and taskbar appear pixelated and unreadable. Is there any way to change this or has Kubuntu likely just installed the wrong driver for my card?

Okay, so here is the deal I have been using Ubuntu for awhile as a network monitoring system and have now changed it to being my main system and was wondering why when my machine is hooked up to my HDTV via a VGA port on the back of VIZIO television, I am only getting a max resolution of 800x600? If anyone can help me with this problem it would be awesome.Any additional information needed please include you terminal commands because I am still just so terrible with those.

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 know this is probably a stupid question , but I started using Ubuntu 11.04 .
My screen resolution on windows was 1600x900
But on ubuntu (even after installing proprietary drivers) the highest I can get is 1024x768 .
I tried using xandr but couldn't work it out .
My xandr info
When i tried adding a new mode using the command
I got the following error
Now I'm not sure what VGA refers to , but Im using a vga port to connect my monitor
Also I'm using only one monitor.

On my Acer laptop wit ATI Xpress 1100 I have a native resolution of 1280 x 800, and Linux Mint 8 (of the Ubuntu family) offers that resolution without a problem. However, a few days ago I connected my laptop to my TV, and since then the correct resolution setting has been LOST. It doesn't appear anymore in the Display settings and so I had to choose a lesser resolution - I am now looking at a less sharp screen! How can I delete it? I hope that I don't need to reinstall...

Pentium 4, 512MB RAM, GeForce2 MX/MX 400
When my machine ran Windows XP, I was able to watch full screen videos on Hulu, etc. with no problem. Now my machine is running Ubuntu (Koala). I'm using Firefox with the most recent Adobe Plugin (and I've made sure there are no other flash players installed). Streaming video (at low to medium resolution) is pretty choppy but still watchable most of the time. It is not watchable when played full screen or with high resolution. When I download the .flv file and play it through VLC, everything is smooth. Are there any tricks I can try to get the video running more smoothly, like it did before? (Disabling desktop effects made no difference.) Should I just get some more RAM? (I realize my RAM is low, but it didn't seem to effect my video watching before.)

I hooked up Lucid to a 50" and adjusted the resolution to the max. Gives a clearer sharper picture but all the displayed items are tiny. Is there something I need to do that I haven't? I went from 1086x720 to 1400(approx)x900(approx) and created the problem. Now I'm back at 1086x720. I'm using the Nvidia 195 drivers.

The installation went okay (to start with) on my newly formatted hard drive (after death of Windows XP), but I got an error about 3/4 of the way through. The system said something about starting the desktop to try to resolve or fault find the problem. So I now have a desktop with access to all the menu system. I am feeling my way around slowly getting used to the environment. I think there are bits missing from the install but with no frame of reference I cannot tell what exactly is wrong. One obvious problem is my Monitor screen resolution. In Monitor preferences it is set as 'unknown monitor'.
The detect monitor button does nothing and the resolution is set as 2048 x 1536 which is just too small to see properly on the screen. I am currently using zoom to increase within a window to use at all. I have tried opening a terminal and using the xrandr command which reports the following:
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 2048 x 1536, current 2048 x 1536, maximum 2048 x 1536.
default connected 2048x1536+0+0 0mm x 0mm

I am have upgraded from 9.04 to 9.10 in my laptop. After performing the reboot, the shell/console resolution went very high and the font size went too small. How to regain the old console shell resolution as in 9.04. I require this urgently as my laptop suffers the white screen problem. Switching between Ctrl+Alt+F6 and Ctrl+Alt+F7 I could get back the screen as the change in the resolution switches off and on the screen, so that I can negotiate with the white screen problem.

I'm running Ubuntu 9.10 on Athlon Barton 2600+ 2.2GHz, 1GB RAM and ATi Radeon X800 computer at 1600x1200 resolution with 2d (no compositing like Compiz).
Looking into the trouble of slow windows resizing I ended up with the observation that for 1280x1024 it's reasonably fast while at 1024x768 it's extremely fast. But 1600x1200 is my LCD's native resolution.
At 1600x1200 my computer is quite slowly responding, resizing windows or moving columns width makes it stumbling, you can see the action clearly does not go right with mouse, it's always late. KDE 4.x is way slower than Gnome.
I've tried many graphic cards (ATi, NVidia) with all possible drivers - open and proprietary, with or without 3d compositing.
Some graphic parameters:
GL_VERSION: 1.5 Mesa 7.6
GL_VENDOR: DRI R300 Project
GL_RENDERER: Mesa DRI R300 (R420 4A4A) 20090101 AGP 8x x86/MMX+/3DNow!+/SSE TCL
Glxgears gives ~4000fps with windowed mode and ~400fps at 1600x1200 maximized window. What is extremely amazing for me is that windowed mode takes 100% processor usage while 1600x200 maximized window (with window decorations) takes 30% of it, don't understand it.
Windows XP seems not to take care about 1600x1200 resolution, it's really fast.

I am piecing a Mandelbrot generator up, I have one working to produce a 1,500 x 1,500 picture (which is fairly accurate).
I would like to increase the resolution over 100,000 x 100,000 + (into the millions x millions).
How I can achieve this? What kind of buffer sizes do I need?
(note this code doesnt have any memory allocations yet)
Here is my code so far:
The program outputs the Mandelbrot as a .tga file. I calculated the image on fixed axis of -2 to 2 (on the x and y axis). Image produced: [url]

I have Fedora Linux 13 64bit system. I use System Monitor to check which process is taking how much memory and cpu. Normally I have dozens of Chrome and Firefox windows open. The Processes tab shows which process is taking how much cpu/ram resources but I unfortunately there is no option like right click and make the window active that matches the PID (the one process that I have currently highlighted). Usually there is a chrome process taking up 30 or 40 percent of CPU while dozens other chrome processes taking much less cpu. I must determine which chrome window ( or any application which has multiple instances running) is taking that much CPU time.

I'm having issues playing HD videos ( some with 720p level, much more apparent with 1080p level one) The video appears to slow then becomes choppy, becoming de synced from the audio that carries on as normal. This occurs with both VLC player and XBMC, though the latter is better. My specs: Fedora 12 3.2 Ghz P4 processor 1Gig ram Radeon 9800 xt gfx card (I couldn't get the 9.3 ati driver to work)

Version: Ubuntu 10.04 Desktop
Problem:
When I change the resolution higher (e.g. 1920x1080),
mouse cursor disappear, until I open the terminal / Ctrl+Alt+F1 (~F6), or run other applications.
But the main problem is, every time after login, the cursor will disappear
(as I know that, before the login, the resolution is 800x600 60Hz, after login, the resolution will be adjusted according to the setting)
So, anyone know how to fix this problem?
I have searched many related posts before,
some of them told me to upgrade the driver, but it didn't help and become worse (cannot boot up, need to re-install ubuntu)
and some of them told me to modify the xorg file, it didn't help, too. (as xorg.conf doesn't exist and I have tried to create one to do the modification, but didn't help)
Any other solution?

With the upgrade to Squeeze and the 2.6.32-5-686 kernel, my Dell GX260's 82845 video chip suffers from the documented intel driver bug (freezes within a few minutes). I tried to fall back to the vesa driver, but am only able to get 640x480 resolution. The monitor is an LG L1720P.
I turned off kernel mode setting (via /etc/modprobe.d/i915-kms.conf), and modified xorg.conf -- added Modeline entries (from gtf) and
additional Mode lines to try to force resolution. Relevant portions of xorg.conf, dmesg and Xorg.0.log are shown below.
xorg.conf:
Code:
Section "Device"
Identifier "Generic Video Card"
Driver "vesa"
