Hardware :: Video - Can't Get The Right Resolution ?
Feb 14, 2011
I'm running Ubuntu 10.04.
I've changed computers.
Previously using nVidia graphics card with proprietary driver.
This computer has an ATI(radeon)card.
In /etc/X11, I have a xorg.conf.backup, three numbered xorg.conf.backup files and a xorg.conf.failsafe file. There is no xorg.conf.
I suppose Ubuntu is booting using the failsafe file, which says the driver in use is fbdev.
Can't get the right resolution.
Since Ubuntu took away the xorg reconfigure method, I'm not finding a way to make it recognize that it's running an ATI card and should use an appropriate driver (radeon?).
Is there any way to get back to just one xorg.conf and it's backup, properly configured, and using the right driver, so I can get the correct resolution?

When I boot my computer I get this message: Warning Pc video resolution is out of range Change setting to recommended resolution 1280x1024 @60mh So I hit ctrl alt f1 I typed in Sudo dpkg-reconfigure xserver-xorg Nothing happens. It's been very frustrating because with everything that I've looked up it says that it's suppose to guide me through something. I desperately need my computer for school.

I've been playing around with Damn Small Linux 4.4.10 on my Dell Inspiron 3000 laptop for quite a while now, and this is the first time I've been downright stumped. To make a long story short, I'm trying to play 480p video on a machine with a 233 MHz Pentium processor, 112 MB of ram, and a Neomagic MagicGraph 128XD graphics card (NM2160). Crazy? Maybe, but I don't think so. I'm using MPlayer set to Xv mode with the XFree86 4.3.0 server, and so far, I've been able to get it to play 360p mpegs with minimal stuttering. However, MPlayer crashes with 480p. This is because the 128XD only has 2 MB of memory, which, after the 1024x768x16 screen takes its share, doesn't leave enough room for a 640x480 overlay.
The creators of MPlayer are aware of this limitation, and suggest adding the following line to my XF86Config file: Option "OverlayMem" "829440"
As I understand it, this is supposed to extend the video card's frame buffer into system memory, thus allowing the higher resolution video to play. However, it doesn't work, based on this output from my XFree86 log file: cannot reserve 829440 bytes for overlay...
Some other suspicious-looking lines from the log file:

I am setting up a MythTV environment to switch from Windows based MediaPortal (with a high number of disturbing bugs). Yet, I have three difficulties, which I want to discuss with you. They are:
- No audio via HDMI see [URL]
- Video resolution seems to change during video playback
- Channels cannot be found via DVB-S [URL]
As you can see, I have created three posts to keep discussions focused.
Alltogether I have the following setup:
- AMD 5050e CPU
- 8 GByte RAM
- Biostar TA890GXE
- Samsung LE40M86BD, connected via HDMI (and only HDMI)
- Mythbuntu 10.10 with proprietary drivers installed
- Technisat Skystar HD2 DVB-S card (two times)
Now, here is the problem:
Whenever I playback any video material using e.g. VLC, the screen resolution changes. This also applies when playback the video in a window and not fullscreen. The problem is that whenever the screen resolution changes, short time later the TV set blanks screen and show the TV set specific information "unsupported video mode".
How can I enforce to stay in the configured video mode?

This system is basically working fine, but I'd like to change the video resolution. It has defaulted to the monitor's native resolution, which is 1920 x 1024. I'd like to set 1600 x 900. However, it's not in the list. In fact, the other resolutions listed in System => Preferences => Monitors aren't even the same ratio -they're more like the old 4:3.
Background: desktop pc with AMD64, 4GB RAM, etc.video is Nvidia Geforce 8200 or 8400installed debian 6.0 with the default "base" or "basic" or somesuch, plus "graphical environment". It's Gnome 2-series I believe.And it seems to be using the Nouveau driver as far as I can tell.So I Googled, and on various pages people said to edit the file: etc/X11/xorg.conf
However, there is no such file on my system. So I googled more, and posters give the following advice: kill the X server, kill the gdm, and then give command: Xorg -configure and this is supposed to generate the config file. However, for me it did not generate the file. Instead it failed with the error message: "Number of created screens does not match number of detected devices".

Debian 8.2 is installed to my Toshiba notebook. There is a performance issue about high resolution mp4 and mkv files. They are not played well on VLC or default media player.I don't see this issue on Windows. This computer has Intel HD Graphics 5500 and i7-5500U CPU.

My name is Mark and I'm new here. I would like to learn how to reduce the resolution on video files. I have MP4 and .avi files that I want to work with. I'm new to Linux but I'm not a computer newbie. I have avidemux on my machine but I can't figure out how to do what I want to do with it.

I can't change the video resolution for Intel 82740 (i740) video card.I'm new to Ubuntu 10.04, as I've just installed it and I have a problem with video settings.I can't change video resolution for my video adapter. I can only choose between 800x600, 640x480,400x300... not 1024x768 for example.No restricted or proprietary drivers...I used Knoppix 5.1.1 Live CD and it automatically set the resolution to 1024x768.I also used Puppy linux 5.1 Live CD and it had a configuration program which also utilised 1024x768.If these versions of linux can utilise the 1024x768 resolution, why can't Ubuntu 10.04

Hopefully this post is here at the right place. I need some information about the GNU shell. I want to write some bash script which is able to sort movie files by resolution of that video. I noticed under GNOME, it's able to view the resolution of a video file by rightclicking clicking on the file and choosing properties afterwards. I would be glad if anyone could tell me which shell-command GNOME uses for this action.

So I have this laptop, and ever since updating to Ubuntu 11.04, the screen will freeze when it turns off to save power, especially if music or video are playing. The screen picture will come up, and the mouse even moves, but I am unable to manipulate anything else on the screen. Sometimes I can hit buttons in the active program, but I cannot see that they are hit. However, when it's a music program or a video, I can hear the sound stop if I hit the pause button. I cannot use the power button to turn it off at this point. I am to do a forced hardware shutdown.
I recently downloaded the a for-pay game, Steel Storm: Burning Retribution, and it also seems to be affected by this bug when it tries to take over the screen. I have managed to close the program by intuition and following sounds, at which point the screen is restored to it's normal settings, but it is frozen and I have to do a forced shutdown. I downloaded several other games to test this out, and many of them then resize the screen have the same problem, though some of them occasionally work and occasionally do not. Of course, the only game that I actually paid for never works.

It's an HP DX2300 running Fedora 13, I think it has NVidea chipset, my other computer is similar machine running Redhat 5.5 and it does 1680x1050 with the same monitor.

I have Centos 5.5 64 bit (with all updates) installed on a new computer that I built, and everything works perfectly out of the box except for the fact that if I try and change the resolution of the display to the max resolution that I can use (aka native resolution of the monitor at 1920 X 1080) using system-config-display, as soon as I log out and log back it in, it reverts to 1280 X 1024. I am very leery of changing the xorg file because this is an expensive monitor and I do not want to trash it, and I have absolutely no experience setting up these video parameters in linux. I did try switching from the vesa driver to the radeon driver using system-config-display, but Centos forced a reconfigure of everything, bringing it back once again to vesa at 1280 X 1024.
I have no desire to to any gaming in Linux, so 2D resolution at 1920 X 1080 using open source drivers would be fine (Whatever the easiest solution would be). I would consider updating drivers, but I my number one concern in doing so would to keep Centos stable. All I ask for is text that is easier to read when I open a terminal, because I work almost exclusively from the command line. My very old computer which is running Fedora 13 and much older hardware has absolutely brilliant graphics in comparison (Obviously newer drivers, kernel, looks like it does not use an xorg file, etc).

How can I lock in a screen resolution setting so Fedora has no other options to use? I had this problem and thought it went away as F11 has been behaving fine for weeks. Today it froze so I had to power cycle to reboot. It came back but had a crappy resolution setting and no higher options available.
I had to re-boot twice to get it to finally load the correct settings again. How can I fix this so it cannot boot to lower resolution? I want to LOCK IN the minimum resolution so it cannot boot to that crappy screen whenever it has a mind to. I feel I should be the one to decide what to load it's my computer !!

I have FedoraCore 12 x86 DVD already installed since the last weekend, no Internet connection available yet for such PC for lack of time to work in such PC. Since two days ago my video resolution has a weird behavior (I only did one configuration change about pass 800x600 to 1024x768) and since there I never did other change video resolution, and with the new configuration I have been using Linux without problems. Now two days ago When I start up the PC and arrive to the login screen I can see clearly that the resolution for my all graphical interface can be 800x600.
After to enter to my account I see the follow behavior, that consist in load the graphical environment and changing to 1024x768 resolution. See my Photo01.png, after that the pointer of my mouse (black row) never is show, I must do something like Photo02.png to see the black row. My only solution by the moment is arrive to the configuration resolution (see Photo03.png) and only do click in Apply button to refresh all the environment and see the desired black row (pointer), see Photo04.png, but I must do this each time when I start up the PC.

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.

Having been using squeeze on my primary system for some time, I decided to install it on my media center PC. After doing a clean install I lost sound (another post) and my maximum video resolution dropped to 1280x1024. I was previously getting 1920x1080 (native) resolution under lenny on this box. So it's a mystery to me why I'm not getting that now. As you can see, the nvidia module is loaded:
# lsmod | grep nvidia
nvidia 9821382 0
i2c_core 12570 2 i2c_piix4,nvidia
PS--This was installed the "debian way" via module assistant.

I'm having a real fight with an Nvidia 6100 video under 11.2. I cannot get anything besides 1024x768 or 800x600 resolution with any technique besides doing an upgrade installation over an existing 11.1 system. I want 1440x900 for this wide screen LCD and that works with the upgrade install but that gets me into other problems with versions and other stuff - not a desireable choice.
OK. I know that the Nvidia driver (190.53) works as all is well under the upgrade. When I do a totally clean installation or a clean install with the existing /home I get a default 1024x768. If I use sax2 to try and change it one of two things happens: the change is ignored or I drop to 800x600 and the ball game is over: I'm stuck there, period. Other than a couple of commented-out lines, xorg.conf is the same as it was or 11.1 (and back to 10.1 after allowing for version changes) after running sax2 but even nvidia-settings won't give anything beyond 1024x768 if I try and use that.
I've been through the how-to stuff and back messages here but I'll be darned if I can force the desired 1440x900. I had a similar issue with 10.2 or so where the only way to get it right the first time was to set the desired resolution to 1440x900 during the hardware setup during the installation but that seems to have disappeared along with xorg.conf which only appears after running sax2. I can't even use the manual diting tricks in xorg.conf I've had to use with some cards - it seems to be completely ignored and I can't see any real problem with it anyway once sax2 builds it. On a couple of machines with later version of the Nvidia video everything is working as expected, at least with GF 6800 and higher video.

New pooter, just installed SuSE 11.1. Would appreciate some insight into which Nvidia driver is right for my system, and what is the maximum resolution I can use without potentially causing any damage (if that's even a real concern).Here are the specifics.
[Code]...
So, now the questions.
a) Should I leave both sets of drivers installed, or should I delete one of them?
b) If delete, which should be taken off?
c) If neither of these drivers is the right one, which do you suggest I get instead?
d) I currently have the resolution set at 1920X1440. Is there any reason to worry that I might be overdriving anything and potentially causing damage to the system?

openSUSE 11.2 (i586)
VERSION = 11.2
on an IBM x3250
Problem is that after the screen comes up to chose the default version or failsafe, my monitor shows no input. If I delete the VGA 0x031 (i think that's the number) on the Options line in the screen where you chose the version, I get my command line interface.
Can I make the blank VGA options permanent?

I'm trying to install Ubuntu Desktop 10.10 on an Intel Atom mainboard (Intel D945GCLF2) with CRT that has been running Ubuntu 9.x previously.
Both, Desktop live CD / installer and alternate install CD cause the screen to go black (and the status LED blinks).
I was able to get a bit further into the boot process with nomodeset as parameter with the Live CD, unfortunately I can't pass GRUB any parameters now that I have used the alternate Install CD by pressing 'e', it just boots.
So now I have Ubuntu installed, I get a terminal with CTRL-ALT-F1 but I don't know what I need to do now or how to adjust resolution or video settings from command line.

haven't been around here in a while, seems that the other OS section is completely gone, so I assume this would be the most appropriate place to ask this, since Debian and Ubuntu are similar enough. Okay, so I installed Debian Lenny on my Power Mac G3. 450MHz, 1GB RAM, and an ATI Rage128, the stock video card. It also has a Linksys WMP54G Wireless card which I got working effortlessly enough.
My issue is with the screen resolution. The driver for the graphics card is installed, but I'm only getting a 800x600 resolution. My Monitor is a 1440x900 screen, so everything's quite out of proportion. I assume I may have to go into xorg.conf to tweak things, but I wouldn't know what to tweak. This is the only thing I need to do to make this my full time OS on this machine.

I need to know a command that is able find the hight and width of a video. I know in VLC you can go into the Codec details but I need something in the command line because I have hundreds of files that I need to organize. I could not find any VLC command that does what I want to do.

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'm currently trying to install 10.10 on my (8-year old) desktop, but I'm getting a warning that says "PC video resolution is out of range. Change setting to Recommended resolution 1924*768@85Hz".
Which would be fine, if I knew how. Is there any way to do this in the installer? I can't get any further than the "Try/Install etc" menu screen.
It has a nvidia Geforce graphics card, if that helps. I can't give you any more info than that because the specs have been lost to the mists of time and old email addresses.

I tried the new flash 10.2 beta in the hopes that they actually improved things, but it doesn't seem like they have.
1) Video's still seem to go to the 0,0 position with multiple monitors. Always the left screen.
2) Clicking on the non-fullscreen monitor still causes the fullscreen to exit.
3) My video is still offset and shifted on players like ....., probably due to screen resolution.

I installed on Aspire One Maverick and then Wine and then Ulead Video Studio. Now Ulead doesn't work, because it need 1024x768, and Aspire One is limited to 1024x600. I tried to install Xrandr and change the resolution of the external monitor to 1680x1050, but the problem still remain.

I installed fedora 14 on Dell laptop but I am unable to change resolution on my laptop also video quality is poor , I think proper drivers are not installed. I am new to Fedora, so probably missing something.

The installer has left me with 1,024 by 768 pixels and a driver that will not reach anything like the res my card and monitor will cope with. The display is currently blanking every 30secs or so for a very brief interval as well.
I may have missed something on the install but there didn't seem to be any opertunity to choose either a driver or monitor type. I was eating my dinner through most of it.
I had a brief flirtation with Mandriva and know that linux should be able to nearly fully support my monitor which is 1680x1050 by Belinea. Earlier open suse install gave the option of seting this sort of thing up and listed all of Berlinea's monitors as well.
The card is an nvidia 210 by Asus. Reported as a 200. I do not want to try installing an nvidia driver yet as I understand that there will be problems. Also I have a YAST ipv6 dns problem = no updates.

I reinstalled my computer with Ubuntu 10.10 and the resolution was fine. I turned off my computer last night and when I turned it on today it's back to everything being huge and the screen resolution being 640 x 480. Then when I try to change it, it says my video card isn't supported. All I want to do is revert back to my stock video card in my computer and remove the nvidia one since obviously ubuntu isn't working with it.

I am trying to find the maximum supported resolution of my video card by using xrandr. My card is an NVidia GeForce Go 7300 (in a laptop). The official documentation does not list specific resolutions that are supported. My laptop display is detected as "AUO" in the NVidia X Server Settings dialog (Ubuntu 10.04 amd64) and has a native resolution of 1280x800. However, I would like to know what is the maximum resolution that I could use on a display with the VGA adapter irrespective of whether the laptop's display is on. This is what I get from xrandr: Screen 0: minimum 512 x 384, current 1280 x 800, maximum 2304 x 864 default connected 1280x800+0+0 0mm x 0mm
1280x800 50.0* 51.0 56.0 52.0
1024x768 52.0 50.0
[code]....
I am guessing the maximum width of 2304 would be for using TwinView with the laptop's 1280-width display next to a 1024 CRT or similar. Surely these cannot be the only supported resolutions. I would like to use a LCD display of width somewhere around 1600 pixels (in particular while turning off the laptop's screen so as to use the external LCD as the primary display) if possible.
