Hi, Is anyone here using TwinView with NVIDIA graphics drivers under CentOS 5? Just tried this configuration (I've been using dual monitors as separate X screens in the past), and while it works in a sense, there are a few issue that will probably prevent me from using it for real. Notably, which screen new applications start on (when using the Applications menu or panel launchers) seems to be quite arbitrary. I expect windows to open on whichever screen I initiated their creation, I suppose, but they will often appear on the other one. This is using the GNOME desktop. Another slight issue is with the notification icons. I really want to display duplicates of these, so I can view them on both screens, but is seems like the Notification Area doesn't work this way, i.e. it will never display more than one of each icon even when there are several instances of the area. But this is a problem I also have when using separate X screens. So, what are other people's experiences with a dual monitor setup? - Toralf This e-mail, any attachments and response string may contain proprietary information, which are confidential and may be legally privileged.

I always have used KDE with it though and KDE has settings for dual monitors as to what screen applications start on, also Kwin has an option to remember where a window was and will always put that application back where it was when you closed it. I mostly used my twins as one giant monitor versus two seperate screens but when i did it worked the same way. As far as the system tray issue i have never tried to have 2 separate system trays running but they have always showed the same icons no matter how i used the trays and panels. There is some very good documentation on nvidia's site about all the possible options you can use for twinview. Its a very long read but it comes in pdf form so at least you can have it locally when needed, mainly because its a long document and it takes time to go through it all. Other than that like i said I have used twins for years and have always enjoyed it. At one time i had two graphics cards and four monitors going at once, it was quite a fun setup, one monitor for irc, one monitor for web browsing, one for vim/emacs/ other various ide's and one for multimedia apps amarok kaffeine etc. I hope you enjoy multiple monitors as much as i do it can take alot of reading and tweaking but once you get a xorg.conf setup the way you want just make sure you back it up so you can keep it with you from machine to machine or from upgrades and such as well. -- LostSon http://lostsonsvault.org CentOS 5.3 KDE 3.5.4-22 -------------- next part -------------- A non-text attachment was scrubbed...

I suppose these issues are desktop environment and/or window manager specific, though, so maybe I'll have to wait for answers from people using GNOME. I might try logging in to KDE just to see how it all works there, though...> also Kwin has an > option to remember where a window was and will always put that application > back where it was when you closed it.This is precisely what I don't want, but the way. If I open an application on monitor 0, then close it, and hit the application's launcher icon on screen 1, I want the application to open on screen one, and not pop up on screen 0 just because that's where it lived earlier.> I mostly used my twins as one giant > monitor versus two seperate screens but when i did it worked the same way. > > As far as the system tray issue i have never tried to have 2 separate system > trays running but they have always showed the same icons no matter how i used > the trays and panels. >I'm not exactly sure what you mean by that... That if you run one system tray then it will generally display all system tray icons? Well, that's kind of obvious isn't it - unless you are used to horribly broken applications?> There is some very good documentation on nvidia's site about all the possible > options you can use for twinview.

My experience with opening apps is that it appears totally random - it is somewhat related to the window least used, but each time I think I have it figured out it does something else. As my xorg.conf is basically the same on both - this may be the reason for identical behavior. I do not recall how I got them setup initially about two years ago - it was a nightmare, thus I keep a copy of xorg.conf and use it. My reading on xorg.conf seems to support the view that this file's setup is black art / black magic. I also understand that some devices can now bypass this ....... i.e keyboard and mouse ..... no logical design in place.

This is a 100% accurate description of what I'm seeing - I couldn't have put it better myself ;-)> As my xorg.conf is basically the same on both - this may be the reason > for identical behavior. > I do not recall how I got them setup initially about two years ago - > it was a nightmare, thus I keep a copy of xorg.conf and use it.Setting it up was quite easy for me, thought, but I used the tools supplied with the NVIDIA driver - these are actually quite good.> My reading on xorg.conf seems to support the view that this file's > setup is black art / black magic.

These are included in the "dkms-nvidia-x11-drv" package at rpmforge.net. Not that this helps me much, though, as I really, really want to be able to work when one of the screens isn't visible (without having to switch the display off and back on all the time.) So it's back to separate X screens I suppose. Which I'm quite happy with, really, but it would be nice to be able to move windows between the screens every once in a while. Actually, the ideal for me would be if the screens could behave as different workspaces.
