Slackware :: Dealing With Two Monitors With Different Resolutions?
Jul 2, 2011
My notebook's LCD runs at 1920x1080 while my external LCD runs at 1920x1200. For the most part I use the external LCD, but there are times when I need to disconnect and use just the notebook's LCD. Because of the different resolutions I need to exit my X session and go back in otherwise the higher resolution of the external LCD gets cut off when I switch to the notebook's LCD. Other than forcing a non-native 1920x1080 on the external LCD, is there any other way to get both screens to show the full desktop without having to restart X? The GPU I have is an nVidia with the nVidia drivers.

I am running Ubuntu 9.10 on an HP laptop with an Intel 82852/82855 GM/GMC Graphics controller. I have a 2nd monitor attached to the VGA port (HP f1703). The problem is that the two screens have different resolutions. the laptop is 1280 x 768 and the other monitor is 1280 x 1024. The xorg.conf file that was created with Xorg -config set both monitors up with 1280 x 1024 resolution so my screen on the laptop looks all "squashed". I have tried to reconfigure it using the Display Preferences dialog but after i re-boot, both screens are unviewable and I have to restore my previous xorg.conf file. I went through the HOWTO: Jaunty Intel Graphics Performance Guide procedure to setup a "safe" configuration but didn't work and I had to restore my "good' xorg.conf file. What do I need to do to setup my two screens with the correct resolutions: 1280 x 768 and 1280 x 1024?
Here is the video portion from my "good" xorg.conf file
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "Monitor Model"
EndSection

I have been trying to configure dual monitors of different resolutions on 11.4 the Nvidia configuration utility does not know where or what to save anything anymore and goes wonky. Trying to use it is a dead end for me. X11 is a mess. What happened to SAX and things like this that were part of openSUSE and just worked? Supposedly we X11 got better. I think it's got over complicated and much worse. This stuff just worked in 11.1 and KDE 3.

So I have been running uvesafb for a while now with no complaints, but klibc hasn't been updated for about a year. I contacted to the author and he said that he will have an update in the coming weeks. However today I was googeling around and to make a long story short, I have successfully been able to get a 1920x1200 console resolution with just the plain old vesafb. This is good news but I am also confused because I've been told many times that is not possible for vesafb to do higher/wide resolutions.

I have been playing around a bit today and decided to hook my tv up to my slack box. I have an NVIDIA gt220 using the proprietary drivers which supports multiple monitors and I can get various setups like an extended desktop and xinerama, but what I can not seem to do, and what I'd actually like to do, is just have both the monitor and the TV display the same images. If it would work better/easier I also have a second NVIDIA card, although it is a different model. I haven't bothered trying that yet as it seems like it would be easier to configure one card instead of two.

What can you do when your linux system "can't find" dynamically linked libraries that are indeed installed in their correct locations? Case in point, I'm trying to run a program called 'ucanvcam':
oliver@human ~/installed/ucanvcam-0.1.6/bin $ ./ucanvcam
./ucanvcam: error while loading shared libraries: libgd.so.2: cannot open shared object file: No such file or directory
oliver@human ~/installed/ucanvcam-0.1.6/bin $ locate libgd.so.2
/usr/lib64/libgd.so.2.0.0
/usr/lib64/libgd.so.2
oliver@human ~/installed/ucanvcam-0.1.6/bin $ ldd ./ucanvcam
linux-gate.so.1 => (0xf7706000)
[...]
libgd.so.2 => not found
[...]
librt.so.1 => /lib32/librt.so.1 (0xf6b1e000)
How can I tell it to look for libgd.so.2 in /usr/lib64? And more importantly, why isn't it looking there, and where is it looking?

I am having trouble with a script that is supposed to : a)take all the jpg pictures in a given directory/parameter and create thumbnails of it in a directory on the desktop.
e.g
from /here/are/the/files.jpg to ~/Desktop/parser-the/files.png. this is my script: all the individual parts work but it falls apart when i put them together.
Code:
for picturesource in $(ls ${1}/*.[jJ][pP][gG])
do
echo this is the picturesource $picturesource;
destination=~/Desktop/parser-"${picturesource}";
echo this is the destination $destination;

I am using Ubuntu 10.04 and trying to get a Novatel USB760 to work. Initially,it is detected as a CD rather than a modem. So, I wrote a udev rule to eject it and that worked, but sometimes the CD comes back and remounts itself and then kicks the modem off and the connection dies. I tried various ways to fix this, but no luck. Finally, I just deleted all the cd files in the /etc/udev/rules.d and the /lib/udev/rules.d (if you don't delete these, udev recreates the files in /etc/udev/rules.d). That does work and now the cd reports hardware errors and does not mount and the modem works as it should.
Now, this works on the device that does not and never will have a CD or DVD attached to it, but on my laptop I don't want to do that as I would not have access to my DVD drive. Does anyone know of a way to make the udev rules ignore specific hardware and not try to create mounts or symbolic links for those devices. Ideally, I would like to blacklist the novatel CD part and not the modem, but I am unsure how or if this is possible.

On my Mac, I use Text wrangler to store all of my html and css code I use to create my web site. So far so good, or should I say so great because I love using Textwrangler. My problem is that when I am aay from my computer or on another computer with another OS, I can't use Textwrangler. I am looking for a way (and I hope this is possible), to store and edit my code online no matter where I am or what computer I am using.

I know it can be done, I just need to know what the hardware is called. There is a community center in the area and I might have a chance to help out. Due to not enough funding the center was only able to get One PC and five monitors. What I hope to be able to do ( and know its possible ) is get the hardware to make each monitor is own terminal with keyboard and mouse.

I have a laptop. At home and at the office I hook it up to an extra monitor for extra screen space. When I do this I add some panels on the second monitor.
When I occasionaly use my laptop op the train, all my extra panels show up on my first screen, which get really cluttered.
If I delete the panels I have to recreate them when I connect my extra screen again.
Is there any way of configuring gnome so that you can easily recreate 'deleted' panels, or configure the extra panels to not show up unless the second screen is attatched ('lock panel to screen')?

I currently work within an RTOS environment without an MMU and thus have access to the entire memory map of whatever application I'm working on. As is common in the embedded world, different parts of the memory map relate to different peripherals or different types of memory. For our next generation hardware, my company is looking at moving to an MMU-enabled processor and using Linux in some shape or form. Most of us in the dept are familiar with Linux, but we are not Linux gurus by any means. So how to explicitly indicate to Linux that we need certain portions of an application to be stored in NVRam and other portions of the application to NOT be based in NVRam has us confused. None of us have a clear understanding of how user memory is delved out by Linux and how we can influence Linux to use specific portions of the memory map at specific times.
For example in this new application, we expect to have 2 memory chips, both that are DDR3 interfaces. One is a standard DDR3 chip. The other is a non-volatile MRAM with a DDR3 interface so it can be accessed by a DDR3 controller and coexist with conventional DDR3 memory. But because the portion of the memory map that the MRAM will represent will be the only portion of non-volatile memory, we are unclear how we explicitly access MRAM addresses in an MMU-controlled environment. My hail-mary guess was that we would want to somehow tell Linux that we want the MRAM's memory space to be mounted as a RAM Drive and then we access that memory as though it is a file on a HD, except it is much higher speed since it will be at DDR3/MRAM speeds. Is there a better, more straight forward way to do this? Coming from an RTOS world, Linux is going to pose some serious challenges for us, but I think it will be the right move once we are all up to speed and are thinking Linux-centric.

I have two NASes. I work off of one, and the other is used as a backup. As I have it set up now, it's slow. Running a backup takes a week. Even for 7 TB, with 1,979,407 files, this seems a bit outlandish,particularly as both systems are RAID-5 and the network is all gigabit. I've been digging about in the rsync man pages, and I really don't understand what differentiates the various topologies.Right now, all the processing is being done on the backup NAS, which has the main volume from the main NAS mounted locally over SMB. I suspect that the SMB overhead is killing me, particularly when dealing with lots of files.
I think what I need is to set up rsync on the main nas as a daemon, and then run a local rsync client to connect to it, which would hopefully allow me to completely avoid the whole SMB-in-the-middle affair, but aside from mentioning that it's there, I can find very little information on why one would want to use the daemon mode for rsync.
Here's my current rsync command line: rsync -r -progress --delete /cifs/Thecus/ /mnt/Storage/input? Is there a better way/tool to do this? Edit:Ok, to address the additional questions: The "Main" NAS is a Thecus N7700. I have additional modules installed that give me SSH, and it has rsync, but it's not in the $PATH, and I havn't figured out how to edit the local $PATH in a way that persists between reboots. The "Backup" NAS is a DIY affair, built around a 1.6Ghz Via Mobo with a Adaptec Hardware RAID card. It's running CentOS 5 with a full desktop environment. It's the hardware I'm running rsync from. (Gigabit is through a additional PCI card).
Further Edit: Ok, got rsync over SSH working (thanks, lajuette!).I had to do a bit of tweaking on my command line, I'm running rsync with the args:rsync -rum --inplace --progress --delete --rsync-path=/opt/bin/rsync sys@10.1.1.10:/raid/data/Storage /mnt/Storage (Note: I'm specifically not using -a, because I want to change the ownership to the local account, to not freak-out SELinux)

I am trying to convert a file using ffmpeg. I have this following code in a terminal.
ffmpeg -i introvideofinal -vcodec libx264 -acodec libfaac introvideofinalfinal.mp4
It returns an error dealing just with the h264 codec saying that I need to use a vpre parameter? I can't find any documentation on using the vpre parameter.

I use a 17" laptop with a 22" secondary monitor running Ubuntu 10.04 LTS. The res on the laptop screen is 1440x900 (16:10) and the secondary monitor mirrors this. Problem is that because the secondary monitor aspect ratio the display is somewhat distorted. It's not so bad that it is unreadable but I work in IT so I am at my computer for around 8hours a day so it wear thin after a while.
Is there a way for me to set different resolutions on each screen? The laptop have an ATI Radeon Graphics card and cannot change the Resolution above 1440x900 even within ATI Catlyst control center.

I'm running Kubuntu, OS Version: Linux 2.6.35-28 generic KDE SC Version: 4.5.8
I have a large monitor, and the max resolution of KDE (1280 x 1024) doesn't fill the screen. That seems rather small for a max resolution. Is it possible to get a larger one?

Under system > preferences > monitor I can select either 640 x 480 or 800 x 600 or 1024 x 768 which are all 4:3 aspect ratios, as my screen is 16:9 everything looks stretched. How can I set a 16:9 aspect ratio screen resolution?

I'm fairly new to Fedora. I am using F14, on a brand new laptop. The LCD screen needs to be matched with a 16:9 ratio, or it stretches everything out. Unfortunately F14 only comes offering three options... none of which are 16:9. Is there an easy way for me to add a 16:9 ratio to my display settings? Does it matter that I am running in low graphics mode?..... it's the only way the liveCd would install.

After struggling with this for 2 days and getting nowhere, I found this simple solution.
1. Download packages http://ajoliveira.com/ajoliveira/gen...it_9.10.tar.gz and http://ajoliveira.com/ajoliveira/gen...rg.conf.tar.gz.
One of these contains the driver files and the other a xorg.conf file.
2. Extract the 2 archives by double-clicking on them.
3. Copy the xorg.conf file to the /etc/X11 directory code...

I have recently installed Ubuntu 10.10 on my computer. The default display driver supplied with it only allowed the screen's default resolution (1280x1024), so I downloaded and installed nVidia's latest driver (260). When I change the resolution to anything lower than the default, the graphics (and most notably letters) everywhere appear slightly blurry, becoming more and more blurry as I lower the resolution. The blur is not terrible, I can still use it but it becomes annoying to watch after a while. I am using a GT240 graphics card, and this problem does not exist on Windows using the same resolution and same driver version.

I am familiar with common video resolutions like 320x240, 640x480 and 720x480. Sometimes I want to use other video resolutions when encoding videos. Is there a formula to calculate the unknown value for the heightxwidth if one value is supplied? For example, if I want my video to be 480xWidth, what value should Width be to get proper aspect.

I just bought a tablet, I would like to VNC to my machine with a lower screen resolution to match my tablet. Right now I use x11vnc on Ubuntu 10.10, and I was thinking to start another session using "startx" but I see there are parameters for display depth but not resolution.

I'm using an HP 2009m 20" widescreen monitor, and have a Nvidia 8500gt video card. Latest Nvidia drivers from RPM Fusion are installed.
My problem is that the only widescreen resolution I have a choice of in both nvidia-settings and gnome's "Display preferences," is 1600x900. While this is fine for desktop apps, my video card doesn't handle games very well at that resolution.
So, I know my card and monitor are capable of displaying other widescreen resolutions (such as 1360x768) because they work in Windows 7, but Fedora doesn't give me the choice of selecting them.
Is there a file that Fedora uses to determine the supported resolutions? How would I be able to select resolutions that I know are supported (at least in Windows 7)? Can editing xorg.conf give me this ability?
I just looked in my xorg.conf, and it's surprisingly slim compared to others I've seen.

Just bought a new 1080p monitor (1920x1080) and it works fine in OpenSUSE 11.3. Problem is before I get the KDE start screen everything is not full screen. Now, I checked the rest of the forums and I cannot find a full list of widescreen or 16:9 grub resolutions.
Does anyone have a list of what's supported?

I'm trying to add a higher resolution to my system. I've tried to edit xorg.conf but I think I'm wrong. Everytime I edit and reboot, it tells me I need to run in low graphics mode for now. Now I'm trying 'xrandr.' I was able to create a new mode just fine, but when I try to add it to the appropriate output, I get this:
Code:
prog@ubuntu:~$ xrandr --addmode LVDS1 1280x1024_50.00

Major opcode of failed request: 149 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 25

Here's what xrandr returns:

I don't know why it puts it in TV1. There's two of them because I tried two different refresh rates.

Linux Ubuntu 9.10 (karmic), Nvidia g-force 5200, Intel(R) Pentium(R) 4 CPU 2.80GHz(old PC but i need learn Linux inside out b4 I go 100% Linux)But I have taken the time to the learn the basic cmds like man mv cp apt-get install etc. I cisco engineer but I want to get good with Linux distro's.I have a NVIDIA G-FORCE 5200 which according to NVIDIA'S website the 173.14.x.x driver is the correct one.I have tried diver 173.14xx. I installed it manually and restarted x server.
I have read the installation guides on this forum but to no avail.When I reboot Compiz cube features are working BUT my screen goes 640x350.I tried to edit the /etc/X11/ xorg. conf file but I cant see any screen resolutions lines. I tried changing NV to nvidia and visa versa. Still the screen is buggered.I installed compiz checker and ran it it said all ok. My text goes large the colours are jittery ? When I go to NVIDIA XSERVER SETTINGS i can not change the screen res ? It just stops from selecting the options? I also tried driver 185.18xx and the same results.I also tried installing the drivers with Envy NG and still no better.I now have installed 96.43.13 NVIDIA driver and my screen has went back to normal but I can not enable the cube effects. I take this means it has reverted back to the graphics card on the motherboard? I have also looked at xrandr -s <1014x768> cmd to manually change it and again no avail.
