Ubuntu :: Displaying 1in Black Border Within Display?
Feb 26, 2010
Has anyone seen or heard of the following problem? I have a 1in black border surrounding my display. I've been running google searches all day without much luck. My current setup is as follows: Ubuntu 9.10 (64-bit), 24in asus lcd, Radeon 5770, amd phenom 2 x4, ddr3 4gb, gigabyte mb. I noticed the border while running the live cd. I figured it had something to do with the video drivers. Last night I installed ATI's linux driver 10.2. I'm getting my preferred resolution of 1920x1080 over dvi. But i'm not able to use my full 24in. It's like using a 20in lcd.

SOLVED: Changed the underscan settings in the Catalyst Control Center. I just installed the ATI catalyst driver 10.7, now there is a black border about 1" on all 4 sides that does not want to go away. Below is my xorg.conf
Code:
Section "Monitor"
Identifier "aticonfig-Monitor[0]-0"
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
EndSection

I upgraded from 9.10 to 10.4 and I get the black border around my desktop. I can't find the scaling option and tried installing the proprietary drivers within Ubuntu and still nothing.

I'm setting up a Dell Inspiron One 2305 and I can't get the native monitor resolution to work without black borders. I'm also experiencing blurry text in Firefox (not sure if this is related). At most other resolutions it will expand to the edges of the monitor fully. Note that the desktop area doesn't extend into the border. I tried glxgears and noticed that it was only pulling 60fps -- figuring it needed drivers I installed the latest ATI drivers. On reboot I was given more options for resolutions however the native one still doesn't work properly. I looked around for troubleshooting tips and looked into xrandr output.
Code:
Screen 0: minimum 320 x 200, current 1680 x 1050, maximum 1920 x 1920
DFP1 connected 1680x1050+0+0 (normal left inverted right x axis y axis) 510mm x 287mm
1920x1080 60.0 + 50.0 30.0 25.0 30.0
1776x1000 50.0 59.9 25.0 30.0
[code]....
Using 'configure display settings' in Gnome, any time I picked a resolution that was 50, it would cause the borders. Any time I picked a resolution that was 60 AND xrandr listed a 60 and 59.9 and said 60 was the selected one, the borders would come back for those too.
So I tried
xrandr --output DFP1 --mode 1920x1080 --rate 59.9
Seeing as every resolution with 59.9 worked. However... This still resulted in borders.

on a 6-7 years old compaq laptop, connected to a brand new hp monitor i am having a mismatch with computer/monitor resolution.
before i had ubuntu 10.04 which could only run in x's safe graphics mode - allowing for full screen resolution but with handicapped graphics - for example videos fullscreen would be quirky and run with cpu at 100%, something which was no problem before 10.04.
then i tried ubuntu 10.10 and later lubuntu 10.10 (which had exactly the same problem); the monitor is running 1440x900 while the computer is rendering to only 1024x768 - leaving a huge black border on right and bottom of screen. the gfx is still crippled; videos fullscreen is quirky as before.

I just scanned a book recently and as what happens in these situations , the borders get dark I just looking for a simple way (prefer command line) to solve this problem maybe, crop pictures for cutting out the borders and then change the dimension (NOT MEAN STRETCH) to regain original size I am not sure , but any others ways that can turn black border areas to white one is fine with me.

openSUSE 11.2 i586, ASUS P3-P5G43 Rev. R1.04G Intel Core2 Duo CPU E8400@3.00GHz, Intel G45/G43 Chipset The Problem: The screen is for the WSXGA+ (1680x1050) standard. This resolution was detected, at the initial install and later with sax2. It shows the desktop with a 1 inch wide black area along the right border of the screen and that is exactly what is missing at the left border (i.e. invisible). It is like the desktop is shifted to the left of the screen. As far as it is visible the image is crisp and clean. Lowering the resolution to 1280x960 works ok, but the aspect ratio is no longer correct. I have checked the archives and found Intel integrated graphics - openSUSE Forums but trying different hints from the thread did not help.

I have three boxes with lenny debian recently installed. I'd like to be able to display X apps running on host1 and displaying on host2. "xhost +" would do the trick for me if I could get it to work but as far as I can tell it does nothing. (BTW, I'm aware of the security risks. This is not a concern for me. I'm safely behind a good firewall. I'm also aware of "ssh -X" but that won't quite solve my problem. See the long version below.) I suspect that Debian secures the xhost command out of the box in some way but I can't seem to figure out what it is. If that is true and someone can show me how to reset it, or direct me to appropriate documentation I think that would solve my problem.
Here's the long version:
What I really want to do is play xbattle with my kids but I need to be able to display the board to three different screens. In xbattle the command line is: % xbattle -red me -blue host1:0 -green host2:0 {and more stuff of no consequence to my question}
This opens a game board for player red locally, player blue on host1 and player green on host2. Or at least it should. If there is a way to make this work with "ssh -X" (or anything else for that matter) I'll be happy to use that instead, but so far as I can tell "ssh -X" only lets me redirect the display back to the one I ssh'd from whereas I need to direct to multiple displays to run xbattle.

How to device-mapper multipathing in conjunction with fdisk. I am more of a solaris expert and now trying to grasp linux (red hat). I have a server that I plan to cluster (future assignment) which is attached to a Netapp SAN via emulex LPe11002 HBA. I have 8 paths to the LUN I created and I can see the multipath device (/dev/mapper/mpath1). Below is my multipath.conf file:
[Code]....
Question 1: When I look at fdisk -l, I can see all 8 paths to the same LUN. Although I partition /dev/mapper/mpath1, I can still see that 7 of the 8 still say "Disk /dev/sdX doesn't contain a valid partition table". I would think that all 8 would have this removed. I execute '/usr/sbin/lpfc/lun_scan all' and it doesn't work. I am looking to clean this up...what should I do? It seems weird to have to do it to all 8 paths!
Question 2: Why does my alias, 'db' not show up under /dev/mappers?
Question 3: Is there a way for fdisk -l to display one lun rather than displaying all 8 paths to the lun?
What is the standard procedure (commands) people execute when adding a new lun to a server with multipathing so it is nice and clean?

Am currently using 8.10 (xubuntu). The machine's "issue" (I've searched for a reference, but the one I found was a forum thread with no answers) is that when the display is set to go to sleep after 8 minutes of idleness in the power manager, it projects a black screen instead.
I'm not sure what different 'power saving modes' a display/OS usually has, but in Windows, when set to 'go to sleep' the screen goes into standby, i.e something like 'no signal', and from what I've read a lot more power is saved in that mode than by simply showing a black screen.
It was the same when I was running 8.04 with a different graphics card, if that matters. Haven't been able to try a different display. Screensaver and timing and resume normal video out works ok.

I installed Ubuntu on a Toshiba Satellite about a month ago. It worked for about three hours. I installed Wine, and it still worked but the display would sometimes go black for a few seconds. Later that day I rebooted and that was it, no more Ubuntu. It goes through all of the process of booting but then the screen just goes black before I even get to the purple Ubuntu screen. I'm running this on a drive in an enclosure so I simply plugged the drive into another machine ( actually two other machines ), and it works perfectly. I have an old Vista drive that I put in the Toshiba and that works just fine, so it's not a pure hardware issue. Just to be sure I wiped the Ubuntu drive and re-installed, this time without installing wine. No Toshiba love. Just the black screen. I even made a flash drive with the loader and iso from the Ubuntu site. Same deal. It starts to boot from the flash and then just goes black where you would normally expect the purple Ubuntu screen. This thing is driving me nuts and I am at a point where I really need this machine working and will be faced with simply wiping the Ubuntu drive and installing Windows.

I have installed ubuntu 10.10 netbook i386 onto a flash drive, but when I go to boot my comp with it I get my initial boot screen, then the ubuntu screen, but then my display goes black.
I dont really know what comp specs to give...

This little guide is for anyone with an HP Touchsmart Tm2 series running Ubuntu 10.04 and above. PLEASE NOTE: These workarounds, solutions, and tips have been tested and verified to work on an HP Touchsmart Tm2-2050us running Ubuntu 10.04 Lucid Lynx and Ubuntu 10.10 Maverick Meerkat. Installation: There are no problems I have experienced with installation except for the display not working on the live USB/CD images occasionally, this can be fixed by simply closing the display lid, and reopening it (this usually has to be done at least 2 or 3 times). Display: Most times after boot up, the display is black. A workaround for this is closing the lid and reopening it (repeat until the display works). Another reported solution is as follows:
1) Open a terminal
2) Type:
Code:
sudo nano /etc/rc.local 3) Add this to the bottom of the file (this disables the ATI part of the hybrid graphics card):
Code:
echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
4) Press CTRL-X (to exit), Y (to save changes), and ENTER/RETURN to accept the file name.
5) Reboot
Note: This solution is also reported to increase battery life.
Trackpad: It may seem that the right click button is disabled, but it isn't. To right click, you must tap the very bottom right corner of the trackpad. Also, by default the trackpad does not have multi-touch enabled (even though it is capable of it). A reported solution for this is:
1) Open a terminal
2) Type:
Code:
sudo nano /etc/X11/xorg.conf.d/50-two-finger-scroll-touchsmart-tm2.conf
3) Add this to the bottom of the file:
Code:
Section "InputClass"
Identifier "enable synaptics SHMConfig"
MatchIsTouchpad "on"

I did a LiveCD to USB install, following the directions I found at [url] When I went to reboot to the USB stick, all I get is a black Screen (monitor is on and lit, just nothing on the display) No cursor or command prompt. I've tried holding shift to bring up the GRUB menu, changing splash quiet to nomodeset, or just adding nomodeset after the splash quiet thing. I've even tried xforcevesa instead of nomodeset still black screen. Looking at the logs nothing is current as of the last time I tried to boot the computer, it's strictly what was written when I installed it to the stick. Other things I've checked/tried, Pressing CTRL+Alt+F1 at GRUB to get TTY, all I get is that blank screen. I've Checked etc/default/grub to ensure the timeout was higher then 0. The Install CD seems to be OK but I have (as it did another install successfully) but I haven't done any throughal checking of it (there was no check this disk on the first screen of the LiveCD) The USB sticks also seem to be ok (in windows though). Using the disk utility on the live CD I did check the file system on the USB stick, the "/" partition came up clean. Anybody have any other thoughts on this install, any thing else I can check?

I am running openSUSE on Acer Aspire-One, 1.6/500MB/8GB and it runs perfectly fine on AC power but whenever I switch to Battery power (on 100% charged state) after sometime (3-5 minutes) the Display goes Black Dead while power light is still green and cpu fan still running and then i have to forcefully shut it down by press and holding power button and restart it.
This is really strange problem and i have fresh installed the openSUSE two times but same problem.

I had my system running fine on Debian for about a month and a half. Then tonight the display suddenly went black. The system was still running, but my screen was black (though the monitor didn't indicate that it had lost signal). I restarted the computer; it booted through the BIOS and showed me my GRUB menu, but then the display went black again. Shorting the jumper pins to clear CMOS data didn't help; in fact, that made the display go black even sooner. Now, I see my motherboard's BIOS splash screen for a couple of seconds, and the display goes black. I know the system is still booting okay, because I hear the usually noises from the internal speaker. But I now have no visual output.
Could this be an issue with the motherboard or the video card? The board doesn't have onboard video, or else I'd try that. And I don't have any spare boards, video cards, or monitors available to me here. I did try using a D-sub cable instead of DVI-D (my monitor and video card support both), but that was no better. What can I do to try to fix this problem?
Motherboard: MSI 870A-G54
CPU: AMD Athlon II X2 250 (at 3.0 GHz, not overclocked)
Video card: Sapphire 100252HDMI Radeon HD 4550

I don't seem to have an "xorg.conf" file.
Gateway SB400a computer with Edubuntu Lucid installed. The problem first cropped up when I installed the Edubuntu packages on Ubuntu. I did a fresh install with Edubuntu and the problem persists. I don't want to go back to Ubuntu since this computer is for my Grandkids and I want to the Edubuntu stuff for them.
I don't have the specs handy, but I can get them. what I have to do to get them. (it happens when you get old)

I've been installing Linux Mint with OSX on a bunch of iMacs, and its been working perfectly excpet for one of the iMacs. The screen will just go black when I boot from a live CD, but I can hear the login sound play. It's strange because all of the other iMac's run the live CD just fine. What could the problem be? I don't know what I can do to troubleshoot this problem.

Just did a fresh install of Natty B1 (previously had alpha 2).. I noticed this issue w/ A2, as well.. plugging in the exterminal monitor (via mini-displayport-to-vga connector) will do the following:
1) turn the screen on the laptop's display entirely black (but not turn it off).. i can move and see the mouse cursor.. but everything on the window appears to not rending or "painted" black..
2) external monitor never becomes active..
the only way to recover is to kill/restart X or reboot after disconnecting the extmon.. having extmon plugged in from boot produces the same results (and it doesn't seem to ever become active during boot up). sometimes this won't happen right away if i plug in the external monitor.. but opening the Monitors system prefs dialog will definitely cause (or detect displays) ,etc I waited to see if the issue would fix itself w/ the beta update, but it hasn't.. Any other 8,1 owners out there that can verify this issue? My (totally uninformed) guess is that it's due to differences in the display/gfx hardware and thunderbolt integration(?)
(I've seen a verification verifications of working-out-of-the-box.. but they were from 8,2 and 8,3 owners (which have discrete graphics cards))... If anyone's gotten this to work with some config stuff, I'd love to see that as well (since the wiki page for 8,1 says it works ootb). If someone could let me know where I should look to capture error output when the above issue occurs, that would be awesome.

This started happening about 1 hour ago. My computer display just went black, and the power light never changed state. I turned off it's power, and then back on (after a few seconds), and the power light came on "blue", which is what it's supposed to be, but i got nothing on the display, and hitting the menu buttons did not show a menu for the display, or any kind of response. i rebooted a couple of times, to no avail.
I thought my new display just crapped out, so i took it to another computer (windows xp laptop) and plugged in the vga cable (my server uses DVI), and it was fine. I took it to another computer (windows 7) with a DVI cable, and it was fine. I brought it back to my desktop/server, and plugged it back in, and it was fine again. Menu buttons and all.
Then, a few minutes later, it went out again. I turned the power for it off for a few minutes, then back on, and it came on with weird scanlines of various colors... then went back to black.
I played with unplugging the dvi cable in the back of the monitor/display, and wiggling it, and then at the computer connection, and at some point it came back on, for no obvious reason (i think i already stopped playing with it).
xorg.log was uneventful, but i can post it, if need be.
Dmesg shows this (the very last line of the NEXT post was the only one of any interest; but googling it returned no scenarious involving display crashes):

F9 has been running great since it came out. I read that one should install F10 before F11 so I did install F10! Everything went great.
(1) Then I tried to install the F11 iso dvd. After the "anaconda started" message at the bottom of a blue screen, the screen went blank and occasionally the message would appear: "cannot display this mode 2:dvi-d". Thinking the monitor had gone into power save, I hit many keys and moved the mouse to no avail.
I gave up! BTW I had checked all media CDs for errors.
(2) then working under F10, a little message appeared from the lower right of the screen asking if I wanted to upgrade to F11.
I accepted and again "cannot display this mode 2:dvi-d" on a black screen after anaconda started on a blue screen. This time no ISO DVD F11. I've never seen such an error message in 11 years (off and on) of using Linux. HD Disk activity was showing on the disk activity light so I let it run all night and part of today. I hit a bunch of keys and moved the mouse and the blue screen returned saying all was done and restarting.
After restart, I seem to have F11 installed. I did a yum update and got some more F11 updates. On the grub screen, the only F11 kernel was the PAE kernel which I selected
and got:
Does F11 have any F11 kernels? BTW running >setup (hd0,0) under F10 grub ruined my XP prof OS on scsi 0 so I reloaded XP Prof from scratch.
Questions:
(1) what is this "cannot display this mode 2:dvi-d"?
(2) Now I cannot boot to Fedora 11 and all the advice on how to reinstall grub has failed failed. Did a rescue and chroot /mnt/sysimage and the fdisk -l
Now XP Prof seems to be on /dev/sdc and Fedora on /dev/sdd. What do I do? In the meantime I have retreated to Fedora 10.

So, I just installed Fedora yesterday. I have been trying out different Linux distros and Fedora was next after Ubuntu and SuSE failed severely. So, I installed F14 yesterday and everything has been great... until I tried to set my JAVA_HOME variable. I followed the instructions here.
After editing $ vi ~/.bash_profile as the site instructs, I proceeded to log-out and log back in...except I can't log back in. I have repeatedly gotten the login screen, selected my account, and entered my password. When I enter my password incorrectly, it says 'Validation Error' and that is not what is occurring. The display goes black for a couple of seconds and I am redirected back to the log in screen.

I want make two simple changes in my display (energy management) & synaptics touchpad configuration:
1.Prevent the display from turning off (getting black) after 1 minute. Of course I checked the energy management configuration, but that has no effect at all.
2.Turn touchpad tapping off. I read Synaptics Touchpad - openSUSE, but the file /etc/X11/xorg.conf does not exist, but only /etc/X11/xorg.conf.install (or is it the same?). Also, there is no section with "driver synaptics" in it. Its content is
