I am working in my Lab with 2 19′ LCD Monitors. I have search Google about this issue when I finished installing Ubuntu 9.04 and I was unable to configure to use 2 monitors.
My desktop computer’s configuration:
- Intel(R) Core(M) 2 Quad CPU Q6600
- DDR3 4GB
- ATI Radeon HD2600XT
After I try to install ATI Drivers supported from ATI website I have figured out how to configure Ubuntu 9.04 to work with 2 monitors and I found some intersting thing as well. In this case, I am using 2 digital ports of those monitors.
Step 1: Install driver
Install ATI Driver from ATI website instead of driver from Synaptic: How to install ATI Graphic driver for Ubuntu 9.04
If you used ATI driver from synaptic, you should disable this by going to menu System -> Administration -> Hardware drivers, and install the driver again.
Step 2: Configure
Firstly, open the Catalyst Control Center by going to Applications menu and choose ATI Catalyst Control Center (super – user) or type this command in the Terminal: amdxdg-su -c amdcccle
In the tab Display Manager, you will be able to config 2 monitors to work Independently by choosing Single (Independent display)
Note that, now you can reboot your system and see what will happend, because you can face the resolution issue that you can’t configure again in the next step. If you got the lower resolution you can change by going to the properties tab on above figure. Don’t worry about that, you can do it.
The interesting thing is you can have 2 monitors work independently. 2 monitors seem to be separate from each other and you can’t drag a application from this monitor to other monitor. If you like this option, you can keep it and don’t need to follow next step.
If you want to drag windows from this monitors to other, you can enable Xinerame feature in the Display Option tab:
Important notice
If you upgrade the new Linux kernel, you might have a display problem, you can fix it by using root terminal at bootup screen to install ATI Driver again based on step 1.
I have success to configure dual monitorss on my system, and enjoy my time hehe.
Have fun.
How to setup Dual Monitor in Ubuntu 9.04 with ATI Driver,
{ 13 comments… read them below or add one }
does not work. ATI drivers are useless shit.
No, it works. I have tried many times.
Can u check and follow steps carefully ?
Best regards,
Thanks for the info.
My only question is why can’t I setup dual screen how it is supposed to be with Ubuntu 9.04 and ATi Catalyst? By this I mean taskbars on the primary monitor, and extended desktop on the other, like any other OS, and like how my Ubuntu behaved before I installed the ATi drivers?
The whole “Single Independent Desktop” thing is not what I want! Grrrr.
I put in the drivers. I have Catalyst regular, and Admin. It tells me ‘to make changes on the display manager page, administrator access is required. Relaunch Ati Catalyst (super user) and enter admin password.’
I have TRIED to launch the catalyst (admin)- nothing happens.
Help? Please?
Hi Brian,
First, download the latest graphic driver from this link and follow those steps.
Second, run this command in terminal:
sudo amdxdg-su -c amdcccleIf there is something wrong, please report here, so I could help you
. Have fun!
I did the terminal coding as you said- and I got this: “no graphical method available for invoking ‘amdcccle’ as ‘root’. I also have installed the software, and followed the steps. I am using Xubuntu 9.10.
Ummm- wha? Does this mean the administrative version of the Catalyst software didn’t get installed properly or something?
I think so Brian. Each time you upgrade your system, you should install it again. Just try to download the latest version and install ^-^
It still refuses to let me use the admin Catalyst settings- and acts like it isn’t there. I even put in the Ubuntu Specific package. Am I not doing something right in the super user dept?
Superb information here, ol’e chap; keep burning the minidhgt oil.
Hello,
Thank you for your article.
I am close.
I have two monitors connected to my ati HD 5450 one on vga d-sub the other dvi.
I have seen the login screen on both monitors. The primary switches with out me making any changes. But when I get in ATI, it only shows one display to configure.
I am on Ubuntu 9.04.
Any assistance would be appreciated.
What the *2$% is this? Keep reinstalling and jumping though hoops to get basic functions to even work? Play with cryptic command line geek code to install a graphics card?
I really want to use Linux but this level of functionality is pathetic! I have mainstream new motherboard and graphics cards from ATI. The dual or 4 screen monitors don’t work, whatever I do. The network works when it feels like it (not often). The sound system isn’t even recognized. The applications all look like something out of Noah’s ark and are barely functional at best.
Sorry, I did try (for weeks) but I am so glad to be returning to Windows 7. Everything works and is 100% stable. No contest.
Linux has about another century to go, then maybe it could be serious competition to Windows 95.
thank you,been try to get dual monitors to work on mint 12,tried everything and nothing work’t.Then i found this tutorial how to do it and now i have dual monitors.if i opened cayalys centre from app with super user it didnt work just kept changing back to old setting,but if you use turminel to open it with the command line you say in step 2,it works ,thank you again
