Hardware :: ATI Multi Card Multi Display Xinerama Composite
Jun 24, 2011
I have an ATI Radeon HD 3300 on-board video chipset, and an ATI Radeon HD 4350 PCI card. What I want is to have both displays available from one mouse/keyboard. I want to play media on one and have the other as my main desktop.The problem is that with Xinerama enabled, KDE desktop effects do not work (KDE says XComposite and XDamage are not available, even though I explicitly enabled them as extensions in the xorg.conf file), and performance is quite bad. Without Xinerama enabled, performance is great, desktop effects work great, but there's a lot of trouble with full-screen video, and the KWin window manager does not apply in the second display (although I can run a second instance of KWin on :0.1).

I am running a multi monitor setup with xinerama, and everything works great except when I try to play an FPS such as OpenArena. The mouse doesn't work, it gets stuck to the screen edge.

Anyone successfully using VNC client on a Mac to control a Debian server?I have the vncserver setup on the Debian machine properly. But I'm having problems connecting to it from both a PowerMac running Tiger and a MacBookPro running leopard.I can connect no problem from a machine running Slack12.2, have not setup port forwarding on my router to connect remotely yet.My Debian machine is running the latest stable release of squeeze with KDE4.I originally tried this with RealVNC Enterprise for OSX but I'm not gonna buy it so I need another alternative after the 30 day trial ends as they have no free version for OSX.
The situation is that I do freelance graphic design on the PowerMac with Cinema4D and Photoshop so I spend most of my time on that machine which is located in my home studio in my attic. Aside from the MacBook and a Dell desktop(family machine)all my other machines and network hardware are in the basement. So to go from the attic to the basement everytime I need to do something on another machine is not practical, and the only other machine I need to access on a regular basis is the Debian box in the basement, this makes the most sense.
I also have a 14 year old living in the house and he's fascinated by all this and will meddle in anything he gets the chance to so all the Linux machines and network hardware need to be behind lock and key.

Now that Ubuntu 10.04 has multi-touch capabilities built-in, if I do not have a multi-touch screen or surface device, can I get 2 USB mice and get 2 pointers on the screen? One for the right hand and one for the left hand as I am ambidextrous, and would find it very convenient to have 2 mice.

Im running 64bit centos 5.6 and using virt-manager.On one of my guest OS's, Windows 7, The max Physical CPUs is 2, you can have unlimited CPU Cores however. (like my machine i use for work has 1, 4 core processor).The issue im having is xen only allows you to set the vcpu arguemnet in your xen config file. How can i set it so that 1 CPU has several Cores just as windows would recognize this machine if i were installing directly to the hardware vs via a VM.Ive searched for 2 days staright trying to address this issue, very little progress, Does anyone know where a XEN support forum is? all i get is the citrix xen support forums.
here is the best info i have found on this, but i dont know how to change this for my CPU to work, when i enter this in my xen config it essentially ignores it and just takes the value of vcpu= so windows shows 2 CPUs each with ONLY one core. Id like 1 or 2 CPUS showing Several cores.The physical Hardware is 2x Xeon 5300 Quad Core CPUs.
> # Expose to the guest multi-core cpu instead of multiple processors
> # Example for intel, expose a 8-core processor :
> #cpuid=['1:edx=xxx1xxxxxxxxxxxxxxxxxxxxxxxxxxxx,[code]........

i would like to know if there is anything like this out there or in development and if not i think there should be. i feel that one of the areas that ubuntu still lacks majorly is when it comes to handling multi display.most people these days are using notebooks and are moving around a lot, and if your like me working as a software dev you need to be able to work from home running a different external display next to your internal, then when you get to work you need to maybe run two external displays or maybe a totally different display next to your internal, sometimes you'll need to connect to a projector in a meeting and do a demo.
At the moment, there is no easy way to do this unless you have a half an hour everytime to configure your displays manually,which goes without saying that its not quite what anybody is looking for.i'm looking for something that works similar to OSX's display manager.where you plug in a screen and poof, its there. and then mayb you can configure what your system should do when that specific monitor is plugged in and it will remember that configuration. so for instance you have a internal 15" with a res of 1440x960 then you want to plug in your 1080p 24", so boom it picks it up but its not configured yet.so it jus mirrors by default, then you decide ok, when this screen is pluggd in, i want it to extend my desktop onto it, and make it the primary monitor. ok cool so its set,so now when you plug it out, your system detects that your display setup has changed, then does a recheck of your active displays, and sets up the appropriate configuration, in this case only the internal is available so it will just go back to the internal, setting it back as the primary and moving all the windows that was on the external back to the internal.i think this would be a invaluable feature for a mobile professional.

I'm having an issue with Vmvware workstation on Ubuntu 11.04. Well, I had many issues, but most of them have workarounds. I can't find any info on this issue. When I have multiple displays enabled (nvidia prop) and launch workstation 7.1.4, my second monitor will become disabled. The unity menu will also stretch out and basically the computer becomes unusable. I have to restart.

I'm trying to get 4 monitors working in Ubuntu 11.04 the way I would like to. I have two Radeon video cards with two monitors connected to each. With proprietary ATI drivers and the Catalyst Control Center I'm able to see all the monitors and Have Multi-Display setups, but they're separated for each video card. I can move items to and from Monitor 1 to Monitor 2, and Monitor 3 to Monitor 4. I'm not able to move windows from 2 to 3 or 4. The two separate display setups have their own set of workspaces too. I've tried enabling xinerama, but when I log back in after a restart the screen is just black and I'm forced to reboot manually. The two separate displays wouldn't be that much of a problem except that my keyboard doesn't seem to work on any application opened on monitors 3 and 4 after I've clicked on something in Monitor 1 or 2.
Below is one of the configs I've been messing around with:
Code:
Section "ServerLayout"
#Screen "amdcccle-Screen[2]-0" 3840 0
#Screen "amdcccle-Screen[1]-1"
Identifier "Layout0"
[Code].....

During my research on enabling composite effects and xinerama, I stumbled upon a few threads and discussions which showed xserver 1.10+ has resolved the conflicts between the 2 modules. I'm wondering if anyone knows of someone/somewhere to get a SUSE compatible build of xserver 1.10+ ? If not, could someone point me toward an easy-to-follow tutorial on how to build packages for SUSE?

According to the Wiki about Xinerama
Quote:
As of the 1.10 X server release, the Xinerama rendering multiplexer and Composite extensions no longer conflict.[URL].. So does this mean that if I use X 1.10 or later, Xinerama and composting can work even over two GPUs and four monitors?

I have a dual monitor setup with a nVidia 7300 card. I'm not sure exactly when this started to happen, but it's happened for a couple of years at least. when I'm in one or the other monitor the cursor will sometimes "stick" in that monitor and refuse to go to the other monitor. it'll just 'wrap around' as when I go to the right part of the monitor, it'll then jump to the left side, and vice versa. Also once in awhile, if I'm in one monitor, the cursor will be taken away and put on the other monitor. I'm just now starting to see a few patterns on what's happening. It's worse if I have VCL playing in the left monitor, (my secondary), and I've got a program maximized in the right (primary) monitor. That's when it'll 'stick' on the right monitor. After I roll up the program or minimize it, then it'll free the mouse. But it's not instant. After it's freed, it still doesn't work exactly. If you click on any program on the left monitor, then you have to move back and forth before the mouse will work on the left monitor.
The second problem I'm having happens only on the secondary monitor. At times the precision is WAY off. For example, if I try to put the mouse right on an icon, and click it. It won't work. But if I move the mouse over to the right or left, suddenly the pop-up comment box pops up, the icon is highlighted and clicking will run the program. It can be off as much as 100 pixels! I've seen these problems in all sorts of GUIs; XFCE, DXCE, KDE 3.x (I never tried it in KDE 4.x since it was nearly unusable) and Gnome. Right now I've only see this on Ubuntu 8.04.01, to 9.10 (I never went past 9.10), and at first I thought it was X since all GUIs had problems. But someone now says that nVidia's driver might be to blame. If you can tell me what command to type in at the terminal, I can supply the current video driver's version.

I'm trying to set up some scripts from one machine that I can use to remotely lock all of my workstations remotely. I have a virtual ubuntu machine ported out to the internet w/ ssh open and I'm using ServerAssistant on my droidX phone to kick off the scripts. I have all of my ssh keys shared between the boxes so I don't have to log on. Everything works beautifully for one machine, a regular Ubuntu 10.10 box with a single video card with 2 monitors. This is the script contents:
Code:
ssh -X brainstem@zappa "export DISPLAY=:0; gnome-screensaver; gnome-screensaver-command -l" But my other desktop, a triple monitor ubuntu studio 10.04 box (2 vid cards) will not kick off with the same syntax as above (obviously different computer name). If I execute the command manually from the remote machine, it doesn't work either. Just to make sure, I ran "gnome-screensaver-command -l" locally on this box just to make sure that part works - it locks the machine locally just fine. I just can't seem to get it to work from another machine. I've tried from 2 different boxes and have the same results. I can do anything else I want over ssh and it all works.

How to identify "Multi Card Slot" hardware? The computer is a Samsung N150 netbook which has an optional "Multi Card Slot". Contacts can be seen inside the slot so the option is presumably fitted. According to the N150 manual it can read SD, SDHC and MMC cards.
There's nothing I can identify as a "Multi Card Slot" reader in /var/log/dmesg or messages and nothing in lspci or lsusb output. I'm no expert on such card readers so the device might be there and I can't identify it. There is a UHCI controller but isn't that only for Firewire? I don't have any of these cards so cannot try booting with one plugged in until I can borrow one.
The reason for wanting to identify the card reader is that I'm building a kernel which only has support for the actual hardware. AFAIK the N150 has no PCMCIA devices so I'm thinking to drop that from the kernel. Is it likely that the card reader is supported via PCMCIA in a similar way to USB drives being supported via SCSI?
Here's lspci output
Code:
00:00.0 Host bridge: Intel Corporation Pineview DMI Bridge
00:02.0 VGA compatible controller: Intel Corporation Pineview Integrated Graphics Controller

I am almost tempted to go back to an old slackware to try this. Anyway, I found a circuit (with just a few resistors) that allows vga output to go to composite input. To my amazement it actually works and it is very clear, but has a double screen. I am told, to fix it you need to change the horizontal sync and or refresh rate for the card. (17 instead of 35). How would I do this in xorg.conf?

I searched around and it seems like other people are having similar issues with multi-touch on Lucid, although my specific problem hasn't been brought up. I have an Eee PC 900A that I upgraded from 8.10 to 10.04. In 8.10, two-finger tapping was processed as a middle click, and two finger scrolling worked perfectly with the other functions.
After upgrading to 10.04, a two-finger tap is now the same as a right click, and middle click is three-finger tap. There does not seem to be any place in the touchpad settings to adjust this.
What's more, if I enable two-finger scrolling in the touchpad settings, the two-finger tapping suddenly stops working. If is change scrolling to edge or disabled, the multi-finger tap functionality comes back again. Has anyone else had this problem? Is there a solution?

I-ve just bought a new hard disk and i wonder what is the best way to do a multi-partition
So my set of drives is:
120Gb - sata
1Tb - sata2
I was thinking to do like this:
1st partition - Slackware Main OS
2nd partition - Arch Linux
3rd partition - /home
4rd partition - swap
5th partition - wind0ws Gaming only
the 120Gb hard drive i intend to do a /home2 for movies, etc. Is that order above the best or i could make swap as 2nd partition

Is it possible to chain together multiple SSH tunnel hops in a single `ssh -L` command on the client side? I have two gateways I need to get through in order to access a remote host. For a normal SSH client connection, it's simple enough chain this all together by simply appending the additional SSH connection commands to the first one:Code: ssh gateway.1 ssh gateway.2 ssh remote.host.

Well this pretty much sums up the experience with Slackware current these days. This is not to say it was all plain sailing. So what problems were there?
1) Nvidia drivers did not work, this was fixed by re-compiling the kernel modules and installing a patched or beta driver, but it introduced another fault. However this problem cannot be accredited to Slackware, all operating systems have driver problems after being updated. Nvidia however had a new version out in a couple of days, which completely fixed the problem.
2) The problem introduced by the hacked fix of the older Nvidia driver wouldn't allow me to switch to the generic kernel (it would not create a valid initrd.gz). I think this was because of re-compiling the kernel modules, so I re-installed them and the problem was fixed. Again not a Slackware fault but a samac fault.
3) Program A couldn't find library B. Slackware has moved some libraries from e2fsprogs to util-linux-ng. This may cause some stuff to break if you are using the multi-lib extensions. This was fixed by creating a compat32 package for util-linux-ng. Again not actually Slackwares fault, but a little closer to home. Alien Bob could you update the massconvert.sh please.
That's it so far, after an update that ran to over 500 lines in the change log, an updated kernel, updated glibc, updates X server etc. etc. and three paltry problems none of which could be attributed to Slackware directly.

I have not checked for a while but did, before posting this, do a search for multi monitor support with KDE 4.4.4 and found nothing.
From what I understand 11.3 is out sometime next month and KDE 4.4.4 is the KDE environment that will be released with that iteration of SUSe.
About a month ago I read about a number of problems with multiple monitor support under 4.4.4. Primarily these issues seemed to be with no more than 2 monitors. The SUSe 11.2 machine here uses KDE 4.3 runs three monitors (Intel core quad, pair of NVidia PCIe graphics cards). I was wondering whether any of the bugs with this type of configuration have been resolved. From what I understood 4.4.4 worked with problems using Twinview but I was not able to find anything that addressed the configuration of having separate X Screens.

I want to code some simple personal projects on the Unix-like partition while doing everything else on my XP partition. Can someone recommend the solution that takes up the smallest footprint in size and processing power that still delivers value? I want to learn how to code in a Unix environment.
I'm trying Cygwin but my first impression is its a bit clumsy. Would a dual boot with BeOS be better? And how would I do it? EDIT: I need to be able to run both OS'es at the same time. This is very important for me. my laptop is pretty crappy and that's why I ask for something that has a low CPU/RAM footprint.

Basically, in most of the WLM versions of MSN Messenger it allows Multi-session, as in I can login into the same MSN account on both my desktop (Windows) and my laptop (Ubuntu). Both Pidgin and Empathy don't, and rather going through all of them I thought I'd ask here.

I know I can just load them on a virtual machine but I will be using different computers and don't want to install it on all the machines.
