T500 dim screen with dual monitors

We have a few T500's that are setup to use the laptop screen and a separate monitor as an extended desktop. For some reason when the laptop goes into lock screen or sleep mode there are a couple of units that when they are logged back into, the monitor on the laptop itself is very dim and the only way to get it to brighten back up is to reboot.
Does anyone have any ideas of what may cause this? I did upgrade one to Windows 7 and have not seen the issue since.
Thanks.

Could it be that the Intel graphics control applet is applying some funky color calibration profile on resume? On my T400, it used to be that a resume would have the Intel applet overwrite Windows' calibration. Preventing some of the igfx___.exe's from starting at boot was a simple workaround.

Full screen with dual monitors

I have two monitors hooked up to my Mac mini. Both displays are working in non-mirroring. I want to be able to put something in "full screen" on one monitor but I still want to be able to do something via the other monitor. Currently if I set a movie playing on I-Tunes to full screen, the other monitor will go dark.
How can I get the set-up to how I want it?

That's annoying, isn't it?
It's why I quit using iTunes in full screen.
I play my movies in VLC and "maximize" the window so I can keep working on the other display. I don't knwo of any other way aorund it.

ITunes Full Screen with Dual Monitor Setup?

This seems like a poor design choice but I can't figure out any way to turn it off. Seems stupid if you can't...
If you have two monitors plugged in and try to watch a movie in itunes (or the visualizer) in fullscreen, it will go full screen on one monitor fine, but it also makes the other one go black and unusable.
Does anyone know a way to make iTunes go full screen in only one monitor without pointlessly rendering my second monitor useless? It would be nice to be able to browse the web or do work on one monitor while having the iTunes visualizer (or watch a TV show) on the other monitor. Quicktime pro does this without any issues.
Thanks.

For your wallpaper drag the window to cover it.
What I mean is that I don't see how you can do what you want, cause when you watch someting full screen you usually don't want to see your wallpaper on your second screen. And that if you want to work on your second screen you won't mind not having it full screen.
QT pro will allow what you want cause it assume that you are working on your movie.

Mac: Full screen on dual monitors still doesn't work with Flash 10.2 upgrade

Recently upgraded to Flash 10.2 specifically for the ability to work on a second monitor while watching fullscreen video on the first. It's still not working at all. The second I click on anything on the second screen, the video jumps back from full screen. I checked to make sure that these sites work properly with dual monitors on a Windows machine. Any tips to get this working? Without this feature, certain websites are completely useless.
Running: MAC 10,2,152,33 on OSX 10.6.6

Hi, I think you are right about it being in this latest FP update. The "More like This" feature on the right hand side of the threads is not working. I think I have some info on Full Screen, but not the dual monitor issue. I'll check to be sure.
I'll try to find some info on it. There were so many changes that came out with this last update.
Will get back to you when I find the info.
Thanks,

How to keep Flash in Full Screen on Dual Monitors

Hi,
I have a simple question. What should I do, to make my application (written in Flex SDK 4.5.1) staying in Full screen when I work in 2nd monitor - like Youtube and Euronews player (http://www.euronews.com/news/streaming-live/) ?
I don't know, how should I embed my application correct or add something to source code to make it work? My application is working correct in Full screen mode, I can use keyboard etc. but I'm not able to make this working - it's always going back to normal when it loose focus.
I have read many topics on this forum and internet, so I'm not interested in solutions like: http://flash-full-screen-multiple-monitor.clangen.com/en/ or .dll tricks like http://lifehacker.com/5419028/keep-flash-videos-in-full-screen-on-dual-monitors
If Youtube and Euronews is working with normal Flash (my current 11.9.900.117) there must be a way?
If someone can type code examples (like for a total dummy ), it will be great.
Thank you.

You'd want to ask in the Flex forum or Flash Professional forum, since you CANNOT edit ANY Flash content with Flash Player.

Full Screen Problem - Dual Monitors - Hulu Desktop

I am using Hulu Desktop with dual monitors. I keep Hulu on full screen on monitor #2. I use monitor #1 for computer use, etc.
It is IMPOSSIBLE to look at an app in full screen mode on monitor #1 and keep my Hulu full screen in monitor #2 at the same time. So if Hulu is playing and I open up a full screen Mail.app...the hulu screen (mon. 2) just shows that grey background.
Apple NEEDS to add a way to make the #2 monitor immune to the spaces functionality. That or make a way so that an app can stay on top of ALL SCREENS not just user-created ones.
I have seen people suggest the, "Right click the app in the dock and choose all screens" but that ONLY works for user-created desktops. It won't make the app be full screen over Mail, iCal, Address book, etc when they make their own spaces window.
Help! :-)\

That's annoying, isn't it?
It's why I quit using iTunes in full screen.
I play my movies in VLC and "maximize" the window so I can keep working on the other display. I don't knwo of any other way aorund it.

Gnome Crashes on Login after messing with dual monitor settings

Gnome displays the sad monitor and has the error message "..something has gone wrong..~" and will force me to log out. I've only started to experience this after messing with dual monitor settings in nvidia. The dual setup(twinview) worked but once I rebooted, I couldn't get it going for awhile.
Here's my xorg.conf

Extra Notes: I have another desktop session with awesome installed(uninstalled now) and could log into that no problem. Awesome was giving me troubles so I uninstalled it. I have 2 gnome desktop sessions, my regular gnome session(the one that crashes), and the other with no window manager(never crashed on startup).
I installed awesome around the same time as configuring the dual monitor setup.
Thanks.

Update.
The crashes are to be expected now. I'm circumventing the whole thing by logging into my other Gnome session without a window manager, logging out and then logging back into my regular Gnome with Metacity.
I've noticed the tty1 sessions(not sure what's it's called) is strange. Apparently my session runs on tty8 but when I try logging in, it'll crash me and tty7 gives me a blank screen with a blinking underscore. The other tty1s work regularly. Not sure if this has anything to do with it.
Is there a way to just reset the Gnome settings?

[SOLVED] openbox margins with dual monitors

Hi community,
I have stumbled to a nasty problem on my first incursion to dual monitors in openbox.
I'm using xrandr with this command (which works just fine BTW):
xrandr --output LVDS --mode 1280x800 --primary --output VGA-0 --mode 1280x1024_60.00 --gamma 1.0:1.4:0.85 --right-of LVDS
and have set a Virtual screen in xorg.conf of 2560 x 1024 pixels.
But, my laptop monitor only handles 1280x800, while my external LCD monitor has 1280x1024, so there is a virtual area under my laptop screen which i'm not using, but i dont really care about that.
The problem is that when I'm setting screen margins, so that maximized windows will respect the panels in the bottom (tint2), in rc.xml (or by obconf) the margins are applied to the virtual screen and only are practical on the external monitor wich has more pixel height.
I'm really missing some kind of per monitor margin settings in openbox, maybe there is and i haven't found it? It makes me wonder because openbox can maximize windows to a single monitor, even if the whole layout it's treated like a virtual screen, so it has some way of distinguishing between them.
I would appreciate any suggestions, thanks.

TL;DR - I'm not aware of any acceptable solution at the moment.
Basically, what you're having problems with, is the "dead area." It can really be quite a pain in the butt if window managers or other screen aware applications don't anticipate it properly. To my knowledge, Openbox doesn't support margins on a monitor-by-monitor basis. In reality, you shouldn't need to be setting margins anyway. Tint2 should be reporting itself as a taskbar, and Openbox should be respecting that.
I have dead area too, with multiple monitors, and Openbox respects both of the KDE taskbars I have running (one on each monitor). (I use KDE and simply replaced Kwin with Openbox.) This tells me that tint2 should be able to cooperate with Openbox. I remember trying tint2 a while ago, and didn't fine it adequate in a dual monitor environment (it was probably a year ago or so). tint2 would need to be setting the _NET_WM_STRUT_PARTIAL hint, and I'm not sure if it is (or if it's doing it properly). See http://standards.freedesktop.org/wm-spe … #id2507618
Also, I do know that the developer for Openbox recently got a dual monitor setup, and she's been adding additional support for dual monitors a little at a time. Hopefully with 3.5, there will be a lot more support. (Margin support for multiple monitors would be great, because it could be a good utility knife for applications that don't care about multi-monitors setups and don't set the proper hints.)
If you're capable of modifying tint2, my course of action would be to try something that works (like the KDE taskbars) and record the hints being set there. Then compare them with tint2 and try to mirror KDE's setup. (If you're a programming lacking experience with X and related nonsense, I'd be more than willing to offer what guidance I have.)
Also, I developed a panel myself (and got pretty far along) using the PyGTK toolkit... But I can't remember if I solved this problem or not. I'll try to check it out and get back to you. (I got as far as implementing a widget system that includes a task list, system tray, clock, menus... It just isn't polished very well. My original intention was for it to be a more robust PyPanel with dual monitor support.)

Interfacing with dual-monitor machine

Hello all--
I've got a G5 at home with dual monitors on which I run 3D animation software with lots of panels. I'd like to be able to control the G5 from work using a laptop (possibly also connected to an external monitor). Is it possible to display both screens of the desktop using ARDv3 on the laptop? Some users have mentioned they can do this but the size of the remote screens is unsatisfactory. So, again, can you visualize both screens well via the remote computer?
Thanks for any help you can offer.

you can view both screens at once but it will be scaled to fit on the screen you have... so what you see is dependent on the resolution of both client monitors and your admin computer's monitor.
you can also select to view a single monitor of the client computer.
i've never run ARD admin on a computer with 2 monitors so i'm not sure how it handles it but i'm guessing that you can view both monitors on both admin monitors.... it'll probably scale down or up dependent on resolution.

Run screensaver independently with dual monitors

I was wondering whether, when running OS X with dual monitors, it was possible to run the screensaver on one of the monitors (while still using the other)?
Cheers,

Nope. Can't do it.

Need to launch Organizer Twice to work with Dual Monitors

If I open a project or either Photoshop Elements 10 or PRE10 and then click on Organizer it loads, but sits in the taskbar below. If I hover over it the AERO Windows (Win 7) pops up showing it's loaded. But It will not maximize. This is when I had last used it on a second monitor so I can easily compare before and afters. However, if I right click on it and close it, then reopen it, it launches perfectly in the 2nd monitor. Does this every time. I ussually leave it open all the time now to avoid this but I don't know how sesitive the catalogs are if the system is rebooted for some reason.
I did no specific configuration for dual monitors, Just dragged it over there when I wanted to use it.
Thanks,
Joe..

Hi Joe,
This is a known issue with dual monitors and got to know that Organizer people are tracking it as a bug for now.
Hope this will be fixed soon.
Thanks

Unwanted keyboard shortcut with dual monitors

Problem:
I have a computer setup with dual monitors (desktop extended). When I have a window open, e.g., Microsoft Word 2007, after I type "1" on the keyboard, the Word Window and mouse relocate to the second monitor. When I type "2" the Word window and mouse relocate
to the main monitor. In the word document, 1 and 2 are typed in the document, but pushing the keys still move the window and mouse to the opposing monitor.
I checked the keyboard settings within Windows and found that sticky keys and such are not enabled. The keyboard has no such features to enable. I also checked the display setup in display properties and found nothing that would indicate such a setup. Google
searches return nothing related to my problem.
What I do know:
-The rest of the numbers on the keyboard work fine. Pressing 1 and 2 on the number pad at the far right of the keyboard do not transfer the active window to the second monitor. Those keys work fine.
-The type of window does not matter. Using notepad, word, excel, internet explorer, sticky notes; all of those windows would transfer to the opposing monitor when I push 1 and 2.
Setup:
Windows XP
Dual-Monitor
Wireless Keyboard and mouse

This pertains to StarTech DVI to USB adapters.
There's an icon in your system tray near the clock, either super utility or usb display device. Right click, and select multi display control panel.

There's a button to disable as long as you have the newer driver from their website. The old drivers had a bug that caused this button to not work

Visualise Spots with dual monitors

I'm finding some eratic behaviour when using Visualise Spots with dual monitors.
I have Development open on one window and the Loupe view open on the other. When I click on the Visualise Spots both windows show the visualisation. When I click the button off - both windows switch to normal view - most of the time.
Occasionally it will switch off in the Development view but stay on the Loupe view on the second monitor. It only goes away when I switch to another image.
Is anyone else seeing this behaviour?
Roy

I have found that's it's linked to zoom level.
I can't quite make out what's going on but the behaviour is very strange.

Screen Sharing problem with dual monitors in 10.6

When I'm using Screen Sharing from my Macbook to my iMac with dual displays (10.6.1 on both machines) It works fine when I initially connect, but when I switch to Display 1, it shows me Display 1, but though my cursor moves, I can't click on anything. It won't let me go back to viewing both displays either, and changing from Adaptive to Full Quality or vice-versa makes no difference, as does Scaling. This happens whether I'm on my local network or using Back-to-my-Mac. It was working fine under Leopard, but has been exhibiting this behavior since the 10.6 upgrade.
Mark

This is a very irritating bug. One thing that has worked for me a couple of times (I think a couple of times it also didn't work) is to turn on mirroring. Screen sharing then only shows one monitor, since they are both the same. I'm not sure if the monitors have to have the same resolution for this to work, mine do. The nice thing about this is that before quitting the screen sharing app you can just turn mirroring off again and it will go back to normal. It's easiest to do this by enabling the 'show displays in menu bar' in your displays preferences.

Screen flickring/blinking on intel 4000 card with dual monitors

Hi community,
I have Samsung series 9 laptop with Intel 4000 card on board. I have two 23" monitors attached to this laptop via hdmi and vga. I have this weird screen flicker issue even on one monitor attached to the laptop.
Tried some tips like i915.powersave=0 on boot load. But seems nothing is working atm. It is not that bad, but very annoying at times specially for eyes.

Any hints for further investigation.
For the record: before having this 2nd monitor i had to turn off the laptop screen off and use only one screen(the 1st monitor). Using one screen at a time does not have any flickers.
It can happen any time and on any screen not restricted to browsers, flash, scrolling etc.
Gnome 3.12.x here.
Thanks
