General :: Mark A Portion Of The Screen As Unusable
Dec 12, 2010
I have a laptop of which a large part of the screen is broken (shows garbage). Fortunately the broken area is a clean rectangle, the bottom 1/3 of the screen or so.
The laptop is running Ubuntu 8.04, but I plan to reinstall it with 10.10. The graphics are provided by an Intel 915GM or something in that direction.
Knowing this, do you know of a way to tell the system about the broken part of the screen, so it will simply not use it? I don't really care whether it's done at the hardware, X or window manager level, though as low as possible is preferred.

And we are unable to restore the setting because the button to click on to do so is outside of the viewable screen! Also we have lost the start bar/dock at the bottom of the screen and cannot figure out how to get it back.

I long while ago (when I was in collage) I used VIM a bit. I have not used it since and would like to get back into using it. I remember there being a way to split the screen within VIM to show common commands on the bottom portion of the screen. I've searched a while and cannot find how to set this up.

I was playing with Compiz on my netbook and installed Fusion. All was well until I rebooted it and now I am missing all effects and a portion of the screen. I am purged compiz and reinstalled it to no avail. I did mess around with the outputs and changed 640x480+0+0 to 1024x600+0+0 but have no changed it back attempting to fix my issue. I have attached an image of the current situation. Basically, I am trying to get my compiz running again with all its sexiness.

I have a laptop with a cracked screen. the crack is not very serious, about an inch and a half on the right. I can still use my laptop but it is hard to see information in the cracked area.
My question is how can i set up ubuntu not to use that portion of the screen, sort of tricking it into thinking that the display is essentially 1.5 inches shorter on the right than it really is.Perhaps setup x11 differently?

Screen flicker Ubuntu 10.10
After installing Ubuntu (Version 10.10 DVD �amd 64Ubuntu 10.10 live DVD).
On the following hardware
Gigabyte GA-K8VT800-RH motherboard
3GB ram
AMD Sempron 3400 cpu.
ATI Radeon X1600 Pro Video card. 256M ddr2 AGP VGA/TV0/DV1-1
p/no 882c85-03
The screen resolution looked very good with all screen resolutions working well The colours and fonts very clear. All other device drivers worked 100%. But unfortunately the display flashes about every 10 seconds and the partial beak up of the display only lasts a fraction of a second and very distracting and is unusable. Testing with Ubuntu 10.10 live DVD. With this months Linux Format Magazine also exhibits this problem. However deleting the partition and installing Ubuntu 10.04 Beta1 DVD -386. And all updates downloaded. Works 100% with no screen flicker.

I attempted to install the mesa-dri-drivers-experimental package and my screen became unusable when I enabled desktop effects. I then uninstalled mesa-dri-drivers-experimental and tried to install the akmod before realizing that my card isn't supported yet. Now I can't seem to do anyting to get my screen back. I removed the blacklist on nouveau, but my screen still goes black after fedora boots. Is there any way I can just get things back to default without reinstalling the whole system?

i've tried both the gnome and kde installers and initially it boots fine to the first menu, but if i then select 'installation' or even try to boot to the live cd, the screen goes blank and then reappears as something that looks like the static on your television if you're trying to tune it in. if you let it continue to boot, then it goes blank again and comes back with a different corrupted screen, but this time you have a white block in the middle that is apparently the mouse point as i can then move it around.
i've tried it in VESA mode and even text mode and the same thing happens. the installation media checks out fine, and my graphics card is brand new - a Radeon 3650 HD. I might try an older version of suse and try and upgrade from there

I installed Ubuntu 10.10 on my laptop and encountered several issues.
1. The Synaptics touchpad is nearly unusable. It is impossible to drag while holding down a button. The cursor will move randomly across the screen instead. It is impossible to right click; a right click is treated like a left click. Double-tapping the dot in the corner does not disable the touchpad.
2. Attempting to change the brightness will kill the screen. The computer is still functioning, and it is possible to perform tasks "blind." Only the screen becomes completely blank.
3. Ubuntu does not always boot up reliably. When it does not, the screen is blank but the computer is otherwise responding.
4. The screen is black after suspend.
5. The computer will sometimes hang when shutting down (showing desktop background). Possibly related messages in dmesg:

I'm using a Gateway LT3103u running a dual boot of Win 7 and Ubuntu 10.10 (separate partitions) and ever since I've started using Ubuntu (last October) I've had persistent graphic card problems.
My graphics card is the ATI Radeon X1270.
Right now I can't use any visual effects because of I do the screen spazzes out and becomes unusable. This isn't a big deal for me since I don't use them but I figured it's relevant to the problem.
Even with visual effects off I still have problems and at times parts of the menu will stay on the screen in a little box which covers any windows that open beneath it. The only way to get rid of it is to turn visual effects on so the screen resets then hit use previous settings.

I recently bought a second monitor and I had this set up perfectly fine with two panels on my primary display and one on my secondary. I've now gone away for the weekend (leaving the monitor) and I went to turn on my laptop and it didn't work.
When I login to a gnome session (or indeed a failsafe gnome session) I just got two horizontal white bars (where the panels would be). I switch to a terminal, login and run top and see that gnome-panel is on 100%. Running 'killall gnome-panel' does nothing (tried a few times).
I've had to install xfce4 just to type this message. Is there any way I can 'reset' gnome-panel or any other fix? Or even a workaround would be nice. I'm on 9.10 by the way. I am going to upgrade at some point but its not really an option yet.

I'm currently studying for my Linux+ test and I'm getting conflicting information regarding the rm -rf command. Yes, I know this a dangerous command, but my question is in regard to how the command functions. In one book I'm studying it says that rm -rf / home/myfolder (there's a space in there) will delete the entire root directory because there is a space between the root and home directory. It says that if there is a spacing such as this, it will ignore anything after the space, so in this case, it would delete the root directory and stop, not that there would be anything left anyway. Then in another book I have, it says that if you did a rm -rf folderName / (with the intention of adding the trailing slash to indicate it is a directory and not a folder) it will delete everything in folderName (assuming it's a child directory of your pwd) and then CONTINUE on and delete the root directory. Now, those two statements contradict each other. When you remove a directory, does the command line ignore anything after a space or not?

I'm coming to emacs from Xcode. An Xcode feature I really like is the ability to type the lines#pragma mark -#pragma mark Section Heading Nameto mark the subsequent part of my code as belonging to a particular section. I can then jump to that section from a drop-down menu.Does a similar ability to break up code into named sections and to jump to a section by name exist in emacs?

I uninstalled mplayer w/ apt-get (and with it mplayerthumbs + mozilla-mplayer) for the purpose of running a 'make install' on an SVN version I compiled - that worked out fine. Now I want to reinstate mplayerthumbs + mozilla-mplayer, but of course in doing so, mplayer is marked as a dep. How then do I mark mplayer to be ignored using the aforementioned package managers? Additionally, why isn't dpkg referencing my sources list?
Code:
[stuart8.5@mepis1 ~]$ sudo dpkg -i --ignore-depends=mplayer install mplayerthumbs mozilla-mplayer
[sudo] password for stuart8.5:
dpkg: error processing install (--install):
cannot access archive: No such file or directory

I had a working ubuntu 10 on my old laptop. Not sure what's happened but now whenever you start any app, the app starts in the foreground, then immediately the desktop gains the focus. This happens all the time on any app that is either already running or started from scratch. Thus making the system unusable.

I have installed fail2ban and it is working great. It is monitoring the auth.log and it's own log. Now here is my question... Every week, my log files rotate, which is just fine for the most part. But this also rotates the fail2ban log and removes any chance of catching a repeated IP from Sunday to Monday. Is it possible to copy a portion of the previous log to the new log?Here is my scenario of what I would like to accomplish, but I am a novice here so please be specific..
logrotate does its job as expected... then a script writes a portion of the previous log to the new log then appends a word/number after that portion (we call this log.1)...next time the log rotates (creating log.2), I want to take the portion of log.1 after the word/number and append it to log.2 along with another word/numberThis will always ensure there is at least 1 week backlog in the logs for fail2ban to track. I don't want to just change the frequency of the log-roll because it doesn't solve the issue of tracking across the log roll

I have a Visio TV that I dropped and cracked the LCD display in one corner, for watching TV it's basically useless now. On a whim I plugged it into one of my computers and about 75% of the screen is still usable. Only the bottom right hand corner of the screen is messed up. What I'd like to do if possible is to define an area of the screen. Say for instance the top left hand corner across and down to where the screen starts getting bad.
Like a left click and drag out the good area and then make only that area "the monitor" for the OS to use. I'd then probably build a case or something to house it in and only show the "live" area to clean things up. I'd like to use Ubuntu. But if you know I can't do it in Linux but can in Windows I'd consider that option as well. I just hate to junk the TV if I can use it some how as a monitor.

Scrot supports capturing a portion of the screen by allowing the user to use the -s option. I need to use the command line.
So I installed xdotool to allow me from the command line to move my mouse, click buttons, type text, select my focus, etc...
I also built a bash script that uses scrot and xdotool that allows me to select the window that has a firefox web page displayed. Then I can position the mouse and do a right button click to position to a data entry box on the web page. Then I can use xdotool type "my text" to input the text into the input box. All this works very neatly.
My problem is the following:
The command "xdotool mousemove x y" does not move relative to the top left hand corner of the focused window. The command moves to the absolute x y screen location, not the relative window location.
This happens even though I use the command "xdotool windowfocus windowid" or command "xdotool windowactivate windowid" to specify which window I want to use (want in focus).
Does anybody know how to specify that the "xdotool mousemove x y" is to move relative to the upper left hand corner of the currently in focus window?
By the way, here is my bash script:
#!/bin/bash
# get window id
WIN_ID=`xdotool search --title MyWindow`
# activate window with title MyWindow

I am still getting the error that no kernel modules are found when trying to load components from the CD on the multi-arch version of Squeeze. Are these even tested prior to releasing them? I mean I know it's testing but I thought we were reaching a release-date and the installer is 100% broken and has been for months. I have a pile of useless multi-arch CDs for Squeeze that won't install on 64bit or 32bit machines due to not finding the kernel modules. Can we get some testing on the installer portion of Squeeze?

I recently installed Ubuntu 9.04 (Jaunty Jackalope) which I then promptly upgraded to 10.04 LTS (Lucid Lynx).
I have a canon pixma MX320 multifunction printer. I downloaded the printer/scanner drivers for linux (debian) from [URL]...asp and installed them with no problems.
The printer function works, as I managed to print a test page, but I was wondering if there was a way to test the scanner portion of my multifunction printer to make sure it works?

When you have a computer whose hard drive is partitioned with one part Windows and the other Linux, what are the concerns with viruses and transference across the two systems? Can viruses infect the windows side brought over through the Linux side (Firefox) or are the partitions completely separated? In other words, if all of your Internet voyages are through Firefox under Linux, is there any danger of infecting the Windows side of the computer? What about when having Linux installed within the Windows portion as a virtual system?

I am an entrepreneur/design engineer so I do a lot modeling, rendering, etc and lot of my programs can only run in Windows. I have a fully licensed version of XP that I want to install on the computer and wondering if it is possible to do the following: Partition a portion of the drive for XP. (VMware isn't the greatest as you lose your 3D acceleration, so I definitely want to do the partition) Install my programs and ensure they run. Use the machine as a virtual desktop remotely?

I have a karaoke disc with (presumably) 10 cdg files on it. I tried to open it with pykaraoke, but it can't seem to read the disc. I then tried k3b, which was able to rip ten ogg files from it (when I created an iso of the disc, it created ten wav files from it.) I tried opening it with smplayer but no luck. kaffeine opened it as an audio disc. When I tried to mount it with a file-manager, it gave the following results:
Code:
read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
[code]....
I tried cdgtools from the pykaraoke site [URL], but I've not had success (cdggui.py requested a "TOC" file to open, but it can't find one on the disc). I use Debian Lenny, but if need be, I'm willing to install newer software (from either source or Squeeze), and I'm also willing, if need be, to use windows software with wine.
