Debian Multimedia :: Resolution Going From DVI To HDMI?
Aug 16, 2011
I recently switched from a DVI cable to a HDMI cable (from the motherboard to the monitor) on my desktop. Everything was working flawlessly with the DVI cable, but when i switched to the HDMI cable the resolution became altered in a strange way. According to both the 'Monitor Preferences' and 'NVIDIA X Server Settings' my resolution is 1920x1080. Both the mouse and some icons looks to be in that resolution. However, the gnome panels, the rest of the icons, toolbars, etc. are huge and in a low resolution. While using Iceweasel, the top gnome panel and the Iceweasel toolbars take up half my screen! I can't find a way to alter the size of these since my resolution is set to maximum. I thought it might be a problem with gnome, so I tried Fluxbox, but the same problems were there. Have anybody else come across this, or perhaps know of a solution?

I'm on Jessie, and use KDE.
Sound keeps coming from laptop's speakers, even when HDMI is connected to an external TV.
I've tried to fix this issue using both Pulse Audio Volume Control and KDE's System Settings -> Multimedia -> Audio and Video Settings. No luck. I've read several topics around, but there are plenty of variables to consider.

I would like my laptop to automatically switch to HDMI (both video and audio) when I plug a HDMI cable in. Running Jessie with Xfce, and I hear that KDE already does this...? I would prefer to stay with Xfce though, and have tried making a UDEV rule and script, taken from the last part of this thread: [URL] ....
At first it worked perfectly, but now for some reason, only Chromium gets resized when I plug/unplug the cable. HDMI output is correctly activated upon cable insertion, but when taking the cable out again, the desktop resolution remains the same (larger than my laptop resolution), so the panels etc. are invisible.

Where the script is for Gnome 3. When I plug the HDMI cable, the desktop expands to include both, but disables the backlight on the laptop monitor. I have to restart gdm3 or the laptop for the brightness control to bring it back up. First, why would it turn brightness to 0, and how do I change the default of that so it stops. I plug and unplug the HDMI regualarly while I wait for a new desktop and the laptop has to pull double duty.
I just switched from Ubuntu 14.10. It never blacked out a screen on plug in or removing. That means that there must be some way to do it, however, it used Unity and this is Gnome 3.
I installed KDE. It works as well. I will use it for now, but would like to get Gnome 3 to work. My default is gdm but I think I saw I can switch it to kdm.

I just got a new Dell monitor (U2715H), and even with beta Nvidia driver (355.06) on Debian testing x86_64, it doesn't detect highest resolution (2560x1440) when connected over HDMI to Nvidia Geforce GT 620. I have an HDMI 2.0 compliant cable, and according to Dell reps, the monitor should support 2560x1440 over HDMI.
Some suggested using xrandr to set the video mode explicitly. I tried doing it, and first got a EDID file with nvidia-settings, and run edid-decode. Where is what I got there:
Code: Select allDetailed mode: Clock 241.500 MHz, 597 mm x 336 mm
        2560 2608 2640 2720 hborder 0
        1440 1443 1448 1481 vborder 0
        +hsync -vsync
So I used those values to make a new mode in xrandr:
Code: Select allxrandr --newmode "2560x1440_60.00"Â 241.50Â 2560 2608 2640 2720Â 1440 1443 1448 1481 +hsync -vsync
xrandr --addmode HDMI-0 "2560x1440_60.00"
But I got this error:
Code: Select allX Error of failed request:Â BadMatch (invalid parameter attributes)
 Major opcode of failed request: 140 (RANDR)
 Minor opcode of failed request: 18 (RRAddOutputMode)
 Serial number of failed request: 31

I have recently acquired a Lenovo Q150 machine and attempting to use it as a HTPC. I've been reading that with this platform a newer kernel is required to make wireless, sound and a few other tweaks work correctly--so I bumped up to testing repositories to upgrade to the 2.6.38 kernel.[URL]...
The audio on this device has been more than a pain. I'm currently using XBMC to play media on this device and after setting the outputs to custom: plughw:1,9 sound is played correctly. I found this out by using alsamixer, selecting the sound card with the F6 key (Nvidia 1) unmutting all outputs, quiting, and running speaker-test -D plughw:1,X where X is the sub-device from the output of aplay -l until sound could be heard from the receiver.
Now my problem is that applications like mplayer, and iceweasel won't output any sound. I'd prefer not to use the optical out on the device and would like to send sound over HDMI. Has anyone had any luck getting it to work as it should?
I've also installed pulseaudio, not too sure if this is really needed. I've also used module assistant before upgrading to compile alsa from source, it worked but i just decided to upgrade the kernel instead of dealing with m-a every time an update comes through.

When I did this in Win 7, the best resolution to use for TV display was 1280x720. When I hook my laptop up in Ubuntu, this resolution is unavailable. Why are there less resolutions available in Ubuntu? Is there a way that I can override this? Lastly, Win 7 will remember to reconfigure my resolution when my TV is connected and then switch it back to the monitor's native resolution when disconnected. Is this possible in Linux? I have to attach screenshots because I'm new to the boards and you need 15 posts to link to sites,

I've just finished installing Ubuntu Server 10.4 onto my ASRock ION330. I don't have a spare monitor lying around, so I've plugged my TV into my machince via HDMI. This works, but the text is tiny. There are too many rows and columns of characters (or equivalently, the font is too small). When I try changing the TV resolution to a smaller size, it just cuts out the rest of the text. So from the command line, how do I make the text bigger?

I just installed Debian 5 onto an older PC and cannot get a better resolution than 800x600. The PC is currently dual booting with Windows XP and in Windows I can get the resolution to 1280x768 without any issues. I checked the device manager in Windows and the video card shows up as VIA/S3G Unichrome II. What do i need to do to get this working at 1280x768 in Debian? I had Mint installed previously and it got to this resolution fine until I upgraded it to a new version, then it was stuck at 1024x768.

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".

FINALLY got my personal server up and running again after my GPU's fan died. i rigged a new fan/heatsink on it but i can't seem to get the resolution correct. nvidia-settings (version 195.36.31) says 1280x960 but i have to pan around the entire desktop (like having a huge image zoomed in on a small screen).

A few weeks ago, I've noticed that my FullHD external LCD (LG Flatron W2243S), which was working without any flaw, can't be setup to reach 1920x1080 anymore, even after a fresh install. My graphics card is Nvidia G105M (I'm using Nvidia proprietary drivers), and I used to configure my monitor with nvidia-settings which usually took something like 30 seconds to setup twinview. However, this monitor is now detected as CRT, and resolution can't be setup to more than 1024x768, which is horrible. I've been trying to use xrandr to setup resolutions, but xrandr -q prints this line:
root@polaris:/home/user# xrandr -q
xrandr: Failed to get size of gamma for output default
(...)
I've been trying several solutions, but nothing worked until the moment. I can find many users reporting this kind of problem across the internet, but any solution.

I just installed Debian 8 (loving it so far) and everything its working right except for one thing: The monitor resolution!
I've got a LG 22 inch monitor and it supports up to 1360x768 but the display settings only shows 1024x768 as max resolution. Doing a little research i was able to get the desire resolution (1360x768) through the use of the tool "xrandr". The problem is that the resolution its not permanent and i need to invoke the xrandr script (i wrote a very basic "script" to set the resolution) on every restart or session logout and of course this is annoying. I've tried to use "crontab" to invoke the script on every restart but for some reason did not worked.
So, making more research i saw that apparently the correct way to set the resolution is by making use of "xorg.conf" but didn't quite get how to do....
Here's the xrandr script that i use:
Code: Select allOUTPUT=VGA1
MODE=1360x768
MODELINE=""1360x768"Â Â 84.75Â 1360 1432 1568 1776Â 768 771 781 798 -hsync +vsyn$
xrandr --newmode $MODELINE
xrandr --addmode $OUTPUT $MODE
xrandr --output $OUTPUT --mode $MODE

I just changed the desktop on my thinkpad from awesome to i3. And now I have some very strange issues with the screen resolution. Because at home I use this x60 thinkpad on a dockingstation and a 19" display. As long as I used Awesome as my Desktop, the display manager as well as the desktop itself could handle the different screen resolution depending on if I'm out with just my 12" on my thinkpad or with the much bigger screen on my home 19" display.
I can understand that i3 maybe cannot handle this alone and I need xrandx to enforce the screen resolution. But why is the display manager (lightdm) also affected by this change? What is so different that even the DM cannot find the proper screen resolution?

I'm running debian lenny and want to change the screen resolution from 640x480 to 1024x768. I'm using a nVidia Geforce FX 5800 and I installed the additional nvidia drivers with the help of this tutorial [URL]. Here is my xorg.conf
Section "InputDevice"
Identifier "Generic Keyboard"
Driver "kbd"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbLayout" "de"
Option "XkbVariant" "nodeadkeys"
EndSection .....
When I try to change the screen resolution via the gnome menu I just can choose the 640x480 resolution and 50Hz refresh rate.

I've googled the issue and had a little luck, though I can't seem to change my xorg.conf file because permissions are defailed. This is the example xorg.conf file I wrote based upon my original and the modifications:

How to enable native screen resolution in X using VESA driver? I have IBM/Lenovo ThinkPad T61 with a native screen resolution of 1680x1050, but I am getting 1024x768 instead.
This is a fresh install of Debian 8.3 (latest stable) (Jessie).
The root cause of this is that nouveau graphics driver (which I was using before) was causing me kernel crashes. Full story here: [URL] .....

I recently installed Debian 5.0 (Lenny) on a Dell Inspiron 1545 laptop. I have been banging my head trying to figure out why my laptop display (15.6" optimum resolution 1366x768) is only running at 1024x768. This was not a problem in Ubuntu even as far back as 8.10 (Intrepid Ibex) which came pre-installed.
I am running kernel 2.6.32 (from Backports) to get WiFi to work and it still hasn't remedied the video oddities.
How do I either:
1) Letterbox the 1024x768 so that it isn't distorted?
or, more preferably,
2) Display in the full 1366x768?
My video card is:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset Integrated Graphics Controller (rev 07)
I also have the xserver-xorg-video-intel driver from the stable repositories installed.

I'm now working to install Debian 8 on another computer since yesterday. Another Linux, and as always, endless list of problems.
- A computer that was freezing at every installation attempt (but never at the same moment) during installation when the Broacom cardbus adapter was connected (it's a chance that it is easy to remove and I found it quickly... and it is working once installation is finished)
- Turning to sleep mode after 15 seconds if I don't quickly try to login
- BOINC receive no work
- Tray icons are here but invisible - no icons, just gray space
- xserver-xorg-video-savage is installed, but I have resolution problems, and weird glittering horizontal lines when the computer is working (as on my other PC with the SiS video card).
On Debian 7.8, it was working fine for having the 1024x768 native resolution of this laptop screen.
But, with debian 8, the max resolution is now "800x600" and with this screen, there is no smooth effect : the image is a disaster.
Here is "lspci -nn" :
Code: Select all00:00.0 Host bridge [0600]: VIA Technologies, Inc. P/KN266 Host Bridge [1106:3156]
00:01.0 PCI bridge [0604]: VIA Technologies, Inc. VT8633 [Apollo Pro266 AGP] [1106:b091]
00:0a.0 CardBus bridge [0607]: O2 Micro, Inc. OZ601/6912/711E0 CardBus/SmartCardBus Controller [1217:6972]
00:0c.0 FireWire (IEEE 1394) [0c00]: Texas Instruments TSB43AB21 IEEE-1394a-2000 Controller (PHY/Link) [104c:8026]
00:10.0 USB controller [0c03]: VIA Technologies, Inc. VT82xxxxx UHCI USB 1.1 Controller [1106:3038] (rev 80)
[Code] ....
How to confirm that my Video card is included into xserver-xorg-video-savage package ? How do I know if the driver is loaded ? How to modify xorg confifugration files in this modern flavour of Linux in order to force adding the 1024x768 resolution ? I already succeed into /etc/default/grub and "update-grub" for the bootloader screen but I want it too in the desktop environment.

I am wanting to try to change my normal user (bbq) to a different screen size within my secondary user (lfs). I was wondering how one would do that.
This happened when OpenClonk changed my screen resolution and when i changed it back my screen blacked out (and me being the idiot save it).
Debian 8 GNOME
Also (a bit unrelated) could a video card problem cause a user to log out? I have been having some severe problems with my monitor and I am thinking it is th video card. Sometimes when I am starting a program my monitor will lose connection to my computer (HDMI signal not found) and I will either have to wait a few seconds and it will turn on or it will just stay blacked out.

I have recently began to use libav and had an issue I was running into.. Not exactly how to word it so I will simply state the symptoms..
Goal: Create a screencast demo on linux, play it back on a windows machine.
I am running this command to record the screen, installed libav:
avconv -f x11grab -r 25 -s 1600x900 -i :0.0 -vcodec libx264 -threads 4 /home/sysadmin/Desktop/output.avi
The issue I am running into is, when I try to play this file in Windows Media Player or even VLC on the linux host, the default size of the video results in the text in the terminal to be unreadable..
When I re-size the video, as in blow it up to full screen, I can see the text clearly..
The playback device is running something like 1280x1020 resolution. Is there a way to make it so that the text will also be readable?

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.
