General :: Getting X11 To Display In 8-bit?
Jun 30, 2010
I've been told to use an old Electron Microscopy program that needs to display in 8-bit.When I install and try to run I get the error
Searching for 8 bit PseudoColor visual ...
Searching for 6-bit PseudoColour visual ...
Searching for 24-bit DirectColor visual ...
No matching visual available.
How do I get Suse 11.2 (my dist.) to show something that has such a requirement? I found something on the web for Mac where they said use xquartz to and quartz-wm but I don't think these work in Suse(?). I also went fooling around on Sax11 and couldn't really find anything.

When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only
export DISPLAY=localhost:0 && xclock
export DISPLAY=localhost:1 && xclock
export DISPLAY=localhost:2 && xclock
[code]....

I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.

I have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).
I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.
I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.

Hi I am new to ubuntu and am having major problems setting my displays up. my setup is a hd TV to the Left of my pc monitor, i have managed to configure catalyst to let me have a main display with the second display being an extension of the first, the problem is i cannot seem to swap my primary display, at the minute my HDTV has all the taskbars and everything on it while my pc monitor is just a blank background, i would like it so i could start a film playing for my children, then drag it across to the HDTV while i can still use my pc in the background.

I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?

I am running a service (Selenium) that relies on launching browsers, even when there is not an active display. So in my startup script, I have
Code:
What is the equivalent code I should put in the shutdown method? In other words, to de-activate the display? Right now, if I restart, I get the errors ...
Code:
server:
Fatal server error:
Server is already active for display 15 If this server is no longer running, remove /tmp/.X15-lock and start again.

Use the following information in your script. Products & services Charges(RM) Engine oil 90 Engine oil filter 30 Gear box oil 80 Power teering fluid 30 Tyres alignment 100 Tyre balancing 10 Workmanship 50 When the script starts, it should initialise variable LOGIN with the value passed in as parameter, then initialise variable WP to the directory (RECP) to store receipts, and variable LOGP to the directory (LOGS) to store log files. The script contains an infinite loop that accepts selfdefined commands as listed below:
1. genp
2. reprint
3. log
4. price
5. bkup
6. !help
7. quit
1. genp
Generates receipt and then displays it on screen. User should input quantity of all products. Initialise the quantity of each product at the beginning of script.....

I am trying to run matlab on a remote mac through my laptop at home, which is a linux-based. I am not able to export the display. Here are the steps I followed.
1. xhost +remotehost
2. Log into remotehost (i.e., the mac machine)
3. export DISPLAY="192.168.2.2:0.0"
4. matlab
But I get the following message,
"unable to open display 192.168.2.2:0.0"
The reason I typed in that ip address in step 3 was that is the ip listed in the "wlan0" block when I typed "ifconfig -a" on my local linux laptop.

I'm testing HTML5 for the first time, using Firefox (beta) 4.0b8 and SeaMonkey (beta) 2.1b1, and its ignoring some CSS. Specifically, I have problems with the <details> tag. (It is nested in a paragraph...I am using it to provide an in-paragraph definition in hopes it can be toggled.)
Firefox only partly supports <details>. It's not supposed to show anything except the content of <summary>, unless you click on <summary>'s content. Instead, it puts a line break before the content of <details>, splitting the paragraph in two peices (which looks silly), without the "closed/open" functionality.
So I tried using "display:inline" in my CSS, but that gets ignored. Just for fun, I also tried "display:hidden" (also ignored) and "display:none" (obeyed).
SeaMonkey doesn't doesn't do anything special with the content of <display>...but it also ignores the same CSS as Firefox.
The only thing I can do to support semantic design is apply "font-style:italic" to all <details> elements.
Granted, you might ask, "why bother using <details> at all. then?" Well, I would like to have <details> for the browsers that support it, with the "font-style:italic" to degrade the page nicely for those that don't (such as for SeaMonkey).
Does anyone know why "display:inline" and "display:hidden" get ignored?

I am struggling to figure out why I cannot display GUI applications from one of the Sun Solaris 10 servers (named espresso) on the network over to my local Linux workstation (beluga). Seems to work perfectly fine when I use my other Solaris 8 (stoli) box for display.Here is what I do, the part that works fine:
stoli: xhost+
stoli: rlogin espresso
espresso: setenv DISPLAY stoli:0.0
espresso: oclock
Now trying the same thing over to linux box, beluga, and it fails with message "Error: Can't open display: beluga:0.0":
beluga: xhost+
beluga: rlogin espresso
espresso: setenv DISPLAY beluga:0.0

I am trying to boot linux kernel from a USB stick. I performed following steps:
1. wrote Grub stag1 to MBR of USB with this command on my linux host.
dd if=/boot/grub/stage1 of=/dev/sdb1 bs=512 count=1
2. Mounted the USB and I copied the following files in my USB.
boot/grub/stage1
boot/grub/stage2
3. Plugged in the USB in the the target machine. Rebooted and changed the booting sequence to boot from USB
My problem is that instead of getting a boot prompt, iIam getting GRUB GRUB GRUB all over the display. I googled out for it and found that if we change the auto-detection oh HDD in bios to manual that may solve the issue, but that did not help. If you happen to know that I am following the correct steps and in right order please point me how can I resolve this issue of GRUB.

I'm trying to connect to my linux server but I'm having some major problems. The server had OEL 5 installed and my local pc is running Windows XP. I'm using PuTTy to connect to the server with Xming running on my loacl machine. I login as root and run the following command - export DISPLAY={ipaddress}:0.0I then run xclock and get the following error - Xlib: connection to "{ipaddress}:0.0" refused by serverXlib: No protocol specifiedError: Can't open display: {ipaddress}:0.0The strange thing is that on my bosses pc (who has got almost the exact same setup ie. PuTTy & Xming) is works perfectly.

which will show a png from GIMP on the screen in fullscreen mode. I was using GIMP and there is an option to save my image as an .h or .c file. I tried .h and it saves it as some kind of very large variable. I want to call this from my own C program and display it on the screen.
