I have been running linux on my thinkpad r50 for about a year, specifically 9.04. The problem is with this new 10.04 lts installation when I go to hook up an external monitor via the avg port and run xrandr to initialize the display, the laptop monitor panel becomes a garbled image and the television that is attached to the computer says no input. As of now I am stumped and open for assistance on this one.
View 1 RepliesBackground: I am running Debian 8 with the Xfce DE on my Toshiba Satellite Laptop.
When at home I will connect my laptop to an external display. I did the same while I was running Ubuntu; however, with Ubuntu I could activate my laptop display by simply disconnecting the external monitor. With Debian + Xfce, unplugging the external monitor leaves my laptop screen blank.
In order to activate my laptop display, I have to open Display settings, turn on laptop display -- which still leaves my laptop screen blank -- and then switch resolution: there are two listings for 1366x768 under resolution, and only the second one restores my laptop display. Please note that if I have both displays on at the same time the size of the output on my external monitor will be reduced to about the size of my laptop's display.
I would like the create a Bash script which can automatically switch between my displays. After some Googling it seems like xrandr is the tool I need for the job. However, I have been having trouble getting it to work.
I tried the command Code: Select allxrandr --output LVDS1 --auto --primary --output HDMI1 --off. This however just turns my external display off without turning on my laptop's display. I suspect this has something to do with the fact that LVDS1 has two modes at 1366x768; perhaps only one of them can actually display? I'm not sure, but anyways here's the output of xrandr:
Code: Select allScreen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 344mm x 193mm
  1366x768   59.99*+
  1360x768   59.80  59.96Â
  1024x768   60.00Â
  800x600    60.32  56.25Â
[Code] ....
Is there a way I can specify that xrandr should use the second 1366x768 mode?
I just realized that the second mode is, in fact, 1360x768 rather than 1366x768...
The good news is that I fixed my problem. It turns out that my backlight was not turning on, giving the appearance that my laptop screen was not displaying anything.
I just installed Kubuntu on my computer running win xp. I have had problems with the resolution because it only lets me set it at 800x600. I have read many of the post here and most of them tell your to use xrandr or xorg config. When i run the xrandr iI end up with a message saying can't open display and also when i try the xorg confing. I installed kubuntu using wubi.

The motherboard - Gigabyte H97N-Wifi - supports that display, although the display drivers are supplied by Intel, and are therefore nonfree. On startup, my display resolution defaults to 1200x800.

I bumped into a webpage which stated that xrandr does not work with proprietary drivers, and if that's true, I can't get it to change resolution on my screen.
I have an ASUS 1000HE laptop running Lucid 10.04 (Desktop not netbook version) which I have connected to an external display (LCD). I don't intend to use the laptop by itself anymore therefore I have configured the display properties to turn off the laptop display and use the external display as primary. However, when the PC enters 'locked mode' or the display powers down after a defined period of time (as set in the properties) when I wake the PC and the display, it turns the laptop monitor back on .... switches the laptop screen to primary display (i.e. with the panels etc displayed on it) and extends the desktop to the external display! The only thing I can then do is go back into the configuration utility and turn the laptop monitor off again and boom, everything is fine and dandy displaying on the external display again! I don't really want to have to do this every time I come back to the PC after it has been locked nor do I want to write a script (if it can be avoided) to deal with it!

Is there some daemon I need to restart to detect the monitor resolutions correctly, or is there a module I can reload?
There seem to several variables to reproducing the behavior. If I restart without the laptop without the monitor plugged in, log in, and then, plug the monitor in with the monitor powered on prior to plugging, all resolutions are detected properly. However, if I plug the monitor in with it powered off, then power it on, I only get the few options shown in above. Once I get the reduced number of options, it seems to stay that way till I restart regardless of how I unplug the monitor.
I have found a work-around by just forcing the modes with xrandr --newmode and xrandr --addmode, but I would much rather have the modes autodetected.
I searched the forums for a long time and could not found any relevant informationI am new to ubuntu (10.10 64bit) and I just want to know if it is possible, like it is in win7 (sorry!), if I can plug in my hdmi cord and have the laptop speakers and display disable, and have the external display and its spears enabled.

View 7 Replies View RelatedMy brother has just installed 9.10 on his Inspiron 6400 and would like to have a dual screen setup using both the laptop display and a flatscreen attached to the VGA socket. Using the standard display options, the two displays are recognised and when the 'mirror screens' option is disabled then settings applied it works to the extent of allowing the cursor to move between the two monitors; however the monitors display nothing except a black screen and the cursor.
I've updated everything to the current version, had a look for restricted drivers (none are suggested by the GUI tool thing) and checked both displays work (both independently and as mirrored). I also had a look for an xorg.conf to poke around in but there wasn't one there.
I'm trying to hook up my TV to my MacBook1,1 laptop running the Lucid Lynx Beta. The TV is connected to the laptop via a mini-DVI to DVI-I adaptor, which is connected to a DVI-I to video adaptor, and this is connected to the TV via a component cable.
Under OS X, after plugging in the mini-DVI cable, the TV automatically becomes a secondary display for the laptop (extending the current screen), so from a hardware perspective everything seems ok. Under Ubuntu, plugging in the mini-DVI cable elicits no response from XRandR whatsoever (xrandr -q reports DVI1 disconnected both before and after). URandR and the regular "Detect Displays" button in the "Monitors" preference app do nothing. The laptop has an Intel GMA 950 chipset, and the Intel driver is running successfully (Compiz works fine). I have a clean xorg.conf (generated by X -configure), except for the addition of "Virtual 2048 2048" in one of the SubSections of the Screen section. I'd be happy to post the full xorg.conf if it would be useful.
So far I have tried xorg.conf tweaks, and I have followed instructions to manually tell xrandr to output to DVI1 as described in the comment by Marko Mikulicic here.
I have been arguing with my acer aspire one laptop since I bought it in terms of the screen resolution and have never been able to solve the problem, although I seem to be getting close. I just updated to 10.04 (the netbook remix).I have been following the instructions for how to fix it here. The result was this:
Code:
liz@Pippin:~$ cvt 1366 768

how Xrandr supports Dual screens. I am attempting to setup Dual Screens on a Ubuntu 10.10 System with an ATI twin head card (DVI + HDMI) Non-mirrored, separate desktops However on connecting a device to the HDMI output - the DVI screen output appears to loose all panels, icons. Only the mouse pointer & desktop background remains.
I believe the output is defaulting from screen 0 to screen 1. I found a solution by creating two devices in xorg.conf and assigning one for each separate screen. BUT this created a new problem of loosing my mouse pointer. how I can get my mouse pointer working or the correct way to setup dual screens.

I am setting up a display system that will not have a keyboard/mouse and automatically boots into gnome and starts up firefox to a display page. The page is optimized to a 720p resolution which I can set when we use a TV for the display, but is not an option if we use a monitor. I am trying to find a way to set the resolution to 720p automatically on boot up. I am always using 16x9 displays with a DVI connection (to HDMI on TVs)
I was able to get one monitor working by creating a script and setting it to load in the Startup Applications as shown:
Code:
#!/bin/bash
scnres="1280 720 60"
modeline=$(cvt -v $scnres | grep Modeline)
modeline=${modeline#Modeline }
[Code]....
I can run xrandr and I get the various modes thatwill supposedly work with my monitor.Then, I run xrandr -s 800x600 and the command tells me thathat mode is unavailable, even though it claims that it is in xrandr -s.What on earth does that mean, then?

Updated old Eeepc 1005HAB to Jessie. Used to have a text file:
xrandr --output LVSD1 --mode 1024x600 --fb 1024x768 --panning 1024x768"
that I could run (twice in a row, it needed) to allow the scroling of the screen to see the bottom 1/4.
This no longer works.
I just switched from Ubuntu to Debian and I am having trouble doing something that I found easy to do with Ubuntu. I have a Radeon R9 graphics card from MSI with dual DVI ports and I'm trying to get xrandr/arandr to detect my dual monitors but it only detects one. I've installed all the drivers and even installed the "amdgpu" driver from the Ubuntu repository but still not detecting. What drivers am I missing?

I have a dual Monitor Setup, both SXGA LCDs, one rotated left. With kernels and Xservers available from debian making settings appropriate kills X and apparently leaves modesetting and keyboard missconfigured - monitors say: no signal and it is not possible to switch to any VT until sysrq-unraw (alt-print-r) is pressed, which makes the system responding to keyboard, but still leaves the screens blank. Restarting the display manager sets a working mode with both screens showing the same.

I couldn't get the right resolution on the external screen (1920/1080) so I disconnected it and rebooted. Now there is only an "unknown" screen in the display menu. I have rewritten the xorg conf file per instructions for enabling GMA500 but to no avail - conf file looks right but screen is "unknown", low resolution and 4:3 aspect ratio, instead of 16:9. How to restore to laptop monitor - I think I can take from there to enable the right resolution.

View 1 Replies View RelatedI am looking for a way to switch quickly and easily between my Laptop Display and my External Monitor, in Windows I had it configured so that when I plugged my Monitor in it would switch to that and when I removed it it would switch back to Laptop Display.

1. If I use the Gnome Monitors instead of ATI Catalist Control Centre it seams to cause some strange issues include confusing Linux on what the max screen res supported by my External Monitor is.
2. When I try and enable/Disable either Display or change Resolution, I am told that I have to reboot before the changes take affect.
I am using ATI HD3200 graphics card, and running Ubuntu 10.04 Lucid on a laptop. It have VGA port so I can attach external LCD monitor to the laptop. I am using fglrx driver.

I have checked varies web resource that saying you can drag and drop the GNOME menu bar to the new screen, it never worked. Someone also suggested to add new bar into the screen and GNOME will remember it, I can't even find the option to do that.
I don't know if it sounds weird but I've been trying for weeks with no result. I want to plug my external monitor through my laptop's vga plug, close the lid and work on my monitor instead of the laptop's monitor.

I can plug my monitor and I have clone displays and it works fine but I can' find a way to shutdown the laptop screen without shutting down the vga outlet.

View 3 Replies View RelatedFew months ago I stood on my netbook running F11 and broke the screen. I don't believe there's anything else wrong with it as the lights and fans act as normal when I turn it on. I hooked it up to a monitor but it doesn't automatically display on the external screen. So I have a pretty odd and possibly quite difficult request. Any step-by-step guide of which buttons to press after turning the machine on, in order to get it to switch to the external display? I just need something along the lines of, press enter, tab, type password, enter, press alt-a, down, down, down, enter, tab, etc. Another possible solution, a very long shot, would be a boot disk that defaults to an external screen?

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.
