Hardware :: Finding The Maximum Supported Resolution Of Video Card By Using Xrandr?

Aug 25, 2010

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


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.

Hardware :: High-resolution Video With 2 MB Graphics Card- Play 480p Video ?

Jun 24, 2010

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:

Ubuntu Multimedia :: Video Card Not Supported By 10.4 64-bits

Aug 17, 2010

I'm working right now with a newly installed Lucid 64-bit. Everything it's fine, but I would like to use the dual monitor for my work, and so I decided to ask to buy me a video card, since what I have now is an onboard graphic that doesn't allow me to do it. I don't need to play games (well I don't think my boss will be happy about it ), and I would rather go for a not expensive solution. But I have some doubts regarding the compatibility with my linux. I found several things on the web, but nothing regarding the video cards that I individuated. If the card is auto detected, it would be better of course.

The cards I was interested are:


But then i've seen on the web you might have problems with ATI in linux and so I went looking also for Nvidia which I found is generally better implemented under linux: ASUS GEFORCE GT 210 512MB DDR2

PALIT GEFORCE GT 220 SUPER 512MB DDR2 I don't have many models among which to choose, because of some conventions at my workplace. The tables of compatibility with ubuntu that I found are all related with much more expensive models, or models that I don't have in my lists. Could somebody tell me if one (or more) of the cards mentioned above work under ubuntu 10.6 64-bit? I have a Hewlett Packard system with:

HP 3674h motherboard
Intel core2 duo 3.16 GHz
250 HD

Software :: Xrandr Not Finding Modes?

Jul 14, 2010

I'm on Debian Squeeze, my PC has a Radeon HD4770 card. I honestly don't know if it's currently running on OS or proprietary fglrx drivers; I installed fglrx, but the control panel app insists the driver isn't loaded. I'm following these instructions to try to get my screen running at 1280x960x85. It's currently at 1280x1024x85, but it's an old CRT that, for some reason, works fine at 1280x960 but gets unfocused at 1280x1024. I'm following the step "adding undetected resolutions", and here's the result:


fallingwater@longcat:~$ xrandr
Screen 0: minimum 320 x 200, current 1280 x 1024, maximum 2048 x 2048
DVI-1 disconnected (normal left inverted right x axis y axis)

Ubuntu Multimedia :: Finding Compatible External USB Video Capture Card

Nov 11, 2010

Does anyone know an Ubuntu 10.10 compatible video capture card that has composite connections for video and audio (yellow, red and white)? It must be external and do its own processing so it doesn't use the computer's own CPU. I intend to capture a live stream and have the Ubuntu PC serve it to other computers. I may use VLC or MythTV. I have looked on various related sites but finding a compatible USB one which does its own decoding is hard to find.

The question I have regarding the specified information ("64/255" logical CPUs) is, which number means what. Does this mean 64 real CPUs with a maximum of 255 cores/hyperthreaded CPUs or something similar or totally different?

OpenSUSE Install :: Monitor Cannot Handle Video Card Resolution?

Feb 4, 2011

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?

OpenSUSE Hardware :: Selecting Video Card Drivers And Screen Resolution On 11.4 KDE

Apr 13, 2011

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.

Ubuntu :: After Installing The Drivers For NVIDIA Video Card It Changed Resolution?

Apr 11, 2011

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.

Installation :: Error 18: Selected Cylinder Exceeds Maximum Supported By BIOS

Mar 29, 2009

I just downloaded the Fedora 10 cd yesterday and decided to install it. I had a partition for Fedora on my system before but I'm not really sure what I did to it. It wasn't booting and it has been so long since I messed with it I just decided to reinstall with the latest (I think I was running F9 previously). So I pop in the live CD, run the install, and then reboot into Ubuntu. I modified my menu.lst to include the new vmlinuz and initrd versions, as well as the new UUID of the partition. Now when I reboot and choose Fedora from grub's menu I get this error:


Error 18: Selected cylinder exceeds maximum supported by BIOS

I found this wiki which does a pretty good job describing the problem:


However, I'm still unable to get this to work. According to many different sites out there this problem shouldn't exist on newer computers. Well, I just recently put a new motherboard into this box -- it's this one:


According to their BIOS page the first release of this was late November 2008. Yes they have had 2 updates since then but it looks like those only serve to support AM3 CPUs (which I don't have) or update some audio playback issues. I seriously doubt I need to update my BIOS to get this to work.

Here's my fdisk:


$ sudo fdisk -l
Disk /dev/sda: 400.0 GB, 400088457216 bytes
255 heads, 63 sectors/track, 48641 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes


I can get Slackware 12.1 to boot (though it kernel panics during startup...not sure what I did to make it angry), but grub immediately fails when I attempt to boot Fedora. Here's the entry from menu.lst:


titleFedora 10 (on /dev/sdb1)
kernel/boot/vmlinuz- ro root=UUID=178bc9f9-76ba-48aa-a588-de978cc1eee1 rhgb quiet


I have verified that the vmlinuz and initrd are both correct. I put the UUID in there after running vol_id so I'm sure the entry is solid. I have tried making it "root=/dev/sdb1" which failed with the same error, and I even tried copying the fc10 vmlinuz and initrd files over to my Ubuntu partition (which controls grub) but for some odd reason the cp command takes a really long time and then I eventually get this weird error for initrd:


$ sudo cp /media/sdb1/boot/initrd- .
cp: reading `/media/sdb1/boot/initrd-': Input/output error

I got the same error with the dd command too. So I was going to just try and copy the files to my sdb3 partition and then modify the menu.lst entry appropriately but that doesn't seem to be plausible at this point.

I have a motherboard that was just released about 4 months ago, an Athlon X2 6000+ CPU, and 4gigs of RAM. The drives are both SATA 300 drives...it's not like this is some old Pentium Pro and the BIOS just doesn't support large drives...this is a brand new system with a very recent BIOS version.

I have successfully quadruple booted all of these in the past, but that may have been prior to the new motherboard. So that makes me think it could be something related to the motherboard but the thing is so much newer than what I previously had, certainly that can't be the problem...can it? Then I remember that Slackware boots, so if it's truly something about how the BIOS can't access some file beyond a particular section of the disk, then it doesn't make any sense that it can book slackware. Fedora is the first partition, Slackware is the last and is like 200+ GB into the disk.

Ubuntu :: Error 18 - Selected Cylinder Exceeds Maximum Supported By BIOS?

Dec 12, 2009

Error 18 - Selected cylinder exceeds maximum supported by BIOS

I am running Jaunty Jackalope on a new machine and after a recent update I got the following message when trying to reboot:

Error 18 - Selected cylinder exceeds maximum supported by BIOS

After reading some of the info on Grub error 18 I decided to create a separate boot partition, as suggested. However, when trying to use Gparted from the live CD to create some space ahead of /sda1, Gparted would run for a while and then crash. The crash message says:

"e2fsck crashed with SIGSEGV in qsort" So now I am stuck, unable to boot from HDD and unable to create new partitions (the other partitions on the disk work fine with Gparted). Could all of this be due to corrupt /sda1 partition?

Debian :: How To Set Display Resolution When Xrandr Cannot Work

Sep 19, 2015

I've just completed my first pc build, and installed Ubuntu 8.2. My build was focussed around a legacy Apple Cinema 30" display, which has 2560x1600 @ 60fps resolution. The motherboard - Gigabyte H97N-Wifi - supports that display, although the display drivers are supplied by Intel, and are therefore nonfree. On startup, my display resolution defaults to 1200x800. This is what /var/log/Xorg.0.log says about it:

Code: Select all[snip]
[     1.830] (II) intel(0): Output VGA1 has no monitor section
[     1.881] (II) intel(0): Output HDMI1 has no monitor section
[     1.882] (II) intel(0): Output HDMI2 has no monitor section
[     1.882] (II) intel(0): Output HDMI3 has no monitor section
[     1.933] (II) intel(0): EDID for output VGA1
[     1.986] (II) intel(0): EDID for output HDMI1
[     1.986] (II) intel(0): Manufacturer: APP  Model: 9232  Serial#: 33555281


I bumped into a webpage which stated that xrandr does not work with proprietary drivers, and if that's true, I can't get it to change resolution on my screen.

I just installed Fedora 12 on a rack computer. I know my screen has the ability to show 1600x1200 pixels. But I don't know what my video card can do. Right now my screen is stuck at 800x600.

Software :: Xrandr Not Changing The Resolution (Debian Lenny)?

Jan 1, 2011

GNOME decided not to use the correct resolution ever. In Ubuntu, it got it automatically and that said it should be 1366x768, and when i run this:


xrandr -s 1366x768

I get


Size 1366x768 not found in available modes

So then I tried to run xrandr and find out what was available and I got:


$ xrandr
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
default connected


So when I try to change it to 1024x768, I get the same "not found in available modes" message.

Hardware :: Limited Resolution Choices In Xrandr With External Monitor On Hotplug?

May 5, 2010

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.

$ 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.

Debian Hardware :: Can't Display Maximum Resolution

Jun 29, 2010

I have a brand new computer with an ATI Radeon HD5850 video card I have a LCD monitor with a native resolution of 1920x1080. I installed Debian Testing 2.6.32-5-amd64

Because I have several machine, I use a KVM (switch keyboard) in the middle. This KVM is quite old but still work correctly only problem is that it don't forward the EDID information. Until now it wasn't a problem, and by specifying the correct parameters of the monitor in /etc/X11/xorg.conf , I always succeed to reach the 1920x1080 resolution

In installed the proprietary drivers from ATI Catalyst 10.6 (last version)

since I have 2 problems :
first in the console I used framebuffer in 1280x1024x32. Before installation of the ATI drivers, it was ok, now the screen is completely black !! on every tty (I didn't investigate much on this trouble yet)

Second problem:
I can't reach the native resolution of my monitor ! No matter what I'm doing, the best the driver propose is 1600x1200 !!

I made a lot of test and modification in xorg.conf but without success, it always goes back to this resolution and never propose something higher For information, if I connect the monitor directly to the video card (removing the KVM), everything is OK and the resolution is automatically set to 1920x1080

Section "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen[0]-0" 0 0
