Ubuntu :: Display Reduces To 1 Line?
Feb 6, 2011
I am using Ubuntu live on a i7 x64 with Zotac nvidia. Not sure if Ubuntu started the issue.
When I am using the PC, suddenly the whole display goes blank except for one horizontal line. Even when I restart, the same line will be only visible.
Then I have to wait for sometime with the PC shutdown. After which the whole display will be back. Not sure what is causing the issue.
I suspect its an issue with the graphics card. But just want to know if ubuntu is contributing to the issue in any way.

Over the course of this year, I've been upgrading my system. Started with a mobo/CPU/RAM/video swap, going to a quad core Phenom-II 955 with 4 Gigs of RAM and an Nvidia GT-240 video card. I then dialed up the clock on that CPU, taking it to 3.415 GHz from its nominal 3.2 GHz, and I overclocked the RAM to 1704 MHz from the system default of 1333 MHz. Then I stuffed another hard drive into the box (the sixth HD in the box). Then I shove another 4 Gigs of RAM into the system, for a total of 8 Gigs.
Over this entire exercise, I have not changed the power supply. It was a Coolermaster 500 Watt supply that has served me well and faithfully. I did a careful power budget of this system and concluded that it was sucking somewhere between 420 and 450 watts at full load. Hence, my PS was very marginal. Allowing for derating as the PS aged, I figured I was really close to the edge.
However, I was having no symptoms, so I went with it. My system sits in a room where the temperature is usually around 28 C, and it would idle with a CPU temperature of 40C. Well, I started having some symptoms that were consistent with inadequate power within the last few days. I wasn't terribly surprised at that, so I didn't complain about having to go and buy a new PS. I purchased a Coolermaster GX 750 Watt supply. This is a high efficiency unit.
Since installing it a couple of hours ago, my system is idling with a CPU temperature of 36C. Mobo temp appears unchanged. No changes to BIOS, overclocking is unchanged, and nothing in the system is different except the PS. The case is an Antec P182, which puts the power supply in the bottom of the case inside its own duct. So, the motherboard and CPU don't see any heat from the PS; all of that is exhausted along its own path.
It is too soon yet for me to know if my symptoms that caused me to change the PS are gone, but the temperature change is quite striking. I have no explanation for it. Does anyone else? Temperature is being reported using the sensors command. Mandriva 2010.1 system. Edit: I am also noticing 1 to 3 degree C drops in hard drive temps, while ambient temperature in this room is constant. There are 6 drives in this box, and their temp history has been pretty constant...

I needed a larger cache because I have some videos stored on another samba server and it's laggy. I set options: cache=20000, cache-min=10 , and that helped to play those videos smoothly, but that caused all 1280x720 mp4 files stored on my local drive to lag and A/V desync with mplayer message: **** Your system is too SLOW to play this! ****
I tried cache values from 1000 to 80000, and they lag in any case. But without the option "cache" these videos play well. Now I commented "cache" in config.
Code:
[default]
#cache=65536
#cache-min=10
ao=alsa
[Code].....

I'm sure this is a very simple task but I don't have a lot of experience with Linux. I need to view what my display adapters settings are, specifically the refresh rate. I have found plenty on how to change the settings but not how show its current setup. I am troubleshooting an vga splitter/extender issue on a digital signage unit where the master screen syncs up but the remote screen does not, I think it has to do with H-Sync V-Sync or refresh rate.

On Solaris UNIX, pressing Ctrl-g displays the line number for the cursor position.
i.e. line 1 0f n* --0%--
But, on suse Ctrl-g on displays the percentage only, not the hard line number
i.e. n* lines --8%--
Anyway I can make vi display hard line just like Solaris?

Normally I use disper to enable my external monitor, but I don't think I can force the 2nd monitor to be primary. [URL]
I've played around with nv-control-dpy included in the nvidia-control source, but I haven't figured out how to do it yet. How to get: [URL]
This is a laptop, to which I connect an external hdmi display when I get to work. dipser -e extends the desktop for me, but the laptop remains the primary desktop (holding the panels etc). nvidia-settings can set primary monitor for me, but I want to use the cli.

Ubuntu 10.04, xsane 0.996, Brother MFC 240c scanner.I just finished writing a long dissertation on my problem with this scanning environment (which I will spare you). In a nutshell the resulting image, when printed, is smaller than the original document. In writing my dissertation for this post I determined that the cause of the issue is that xsane believes I am scanning an 8.5 x 14 inch document when I am in fact scanning an 8.5 x 11 letter. So the question is... can I change the size to 8.5 x 11? and if so, how? I have not found anything in the xsane Preferences.

I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.

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 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.

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 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.

After running the following command, I get:
[root@yukiko /]# find / -iname .bashrc
/home/clamav/.bashrc
/home/vpopmail/.bashrc
/etc/skel/.bashrc
/root/.bashrc
But I would like to have a command that prints a specific line by supplying the command with the line number, for example:
[root@yukiko /]# find / -iname .bashrc | getline(2)
/home/vpopmail/.bashrc
Is there such a command on CentOS?
