I have a pretty powerful desktop running fedora and was wondering if I could use the new SPICE VDI technology to create a dummy terminal virtual desktop using just a 2nd monitor, keyboard, and mouse (no thin client). Is this possible using USB ports? Would I need a 2nd video card for the monitor?
View 1 RepliesLong story short - on my laptop, touch pad is recognised as PS/2 mouse. Everything works (moving, clicking, dragging, vertical scroll). But I often accidental click the pad while typing.Synaptic driver recognises it as ALPS glide point it seems (synclient -m 1 gives me back only x,y difference for the gestures, but X,Y coordinates are always 0,0) - so then I get everything right including disabling mouse on keyboard input - but scrolling doesn't work So I came up with 2 possible ideas - which I don't know how to do/test:1. Perhaps there is a way to disable mouse input while typing without synaptics drivers?2. Create a dummy input device (mouse), and tie synaptics driver to it. Add another input device in xorg.conf to point to the real touch pad as PS/2. And make the synaptics disable "real mouse" by enabling GuestMouseOff option.

View 4 Replies View RelatedSPICE has been getting there for a while now and seems to be a very capable mechanism for running remote desktops. (You see where I'm going?) Virtual desktops have a good chance of becoming all the rage if SPICE gets a low enough latency implementation. But what about applying that low latency implementation to running over a physical layer? Who says the host machine has to be a virtual box? (See where I'm going now?) Does anyone know if I can start using SPICE as an alternative to NX for example?

View 3 Replies View RelatedInstalling spice is my first attempt at compiling anything from source and it has been an incredible headache so far. After going round and round for 3 hours chasing missing dependencies I'm finally stuck at a place where I don't know how to proceed. According to the instructions I'm following: "In case of an older kernel (version < 2.6.30)Get kernel sources using the following git repository:
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-2.6.30.y.git
cd <spice_root>/vdesktop/kernel
./configure
ln -s <linux-2.6.30 source dir> linux-2.6
make sync
make "
Unfortunately my CentOS box (the one I'm working on) doesn't have internet capability, so I have to download everything on my windows box and burn it to cd. So I downloaded the 2.6.30 source from kernel.org, copied it to my CentOS box and unpacked it. I got as far as "make sync" in those instructions before I hit the next snag. When I tried to "make" it gave me an error "/lib/modules/2.6.18-194.el5/build no such file or directory"When I look for the referenced "build" file, it says link broken and when I follow the link to "/usr/src/kernels/2.6.18-194.el5-x86_64" which does in fact not exist.
So a quick google search reveals I need the source for my current kernel in addition to the 2.6.30 kernel source. The instructions here:
[URL] for the full kernel source look hugely complicated and involve rpms which is something I know nothing about. I tried to yum install kernel-devel hoping that would appease the unhappy make build, but I'm limited to installing things on the CentOS install DVD and yum tells me "error downloading packages" from the DVD repo, so I guess the source files are not the DVD? To top it all off, I only have 30 Mb of free space left on this drive anyhow, so I don't think there is room download the whole source anyway unless I put it on cd and mount it or link to it somehow in ways that make my tired brain hurt.
Spice server/client configuration. I used remote viewer on debian jessie to connect to a guest virtual machine on kvm and everything works fine. It used a spice server / client and qxl. After I upgraded to debian stretch, I suddenly face issues with black bars in the remote client window. Those black bars appear only on the left and right side of the remote viewer window. Also in full screen mode the black bars sadly appear. Maybe the scaling mode is somehow disabled or my screen resolution of the host was wrong calculated related to that i can change the guest screen resolution but the spice remote client keeps its window size with the black bars. I was trying the last couple of days to resolve this issue, unfortunately without success.

View 4 Replies View RelatedConsider that symbolic links at times can be broken. The target reference can be lost or misplaced. As such, usage of a symbolic link becomes deterred or broken. I propose the following: Symbolic links from now on carry a checksum relating to the original file they are linked to. The original file will carry a property that checks if it has been changed. This property will figure out the new checksum, reconfigure the symbolic link, and continue the symbolic link. Furthermore, if the system were to change, there would exist the possibility of have a symblink-comparison feature that allows the user to check the entire filesystem for files that meet the checksum criteria so that symbolic links can once more be re-established.
View 2 Replies View RelatedI've just bought a 6-core Phenom with 16G of RAM. I use it primarily for compiling and video encoding (and occassional web/db). I'm finding all activities get disk-bound and I just can't keep all 6 cores fed. I'm buying an SSD raid to sit between the HDD and tmpfs. I want to setup a "layered" filesystem where reads are cached on tmpfs but writes safely go through to the SSD. I want files (or blocks) that haven't been read lately on the SSD to then be written back to a HDD using a compressed FS or block layer.
So basically reads:
- Check tmpfs
- Check SSD
- Check HD
And writes: - Straight to SSD (for safety), then tmpfs (for speed) And periodically, or when space gets low: - Move least frequently accessed files down one layer. I've seen a few projects of interest. CacheFS, cachefsd, bcache seem pretty close but I'm having trouble determining which are practical. bcache seems a little risky (early adoption), cachefs seems tied to specific network filesystems. There are "union" projects unionfs and aufs that let you mount filesystems over each other (USB device over a DVD usually) but both are distributed as a patch and I get the impression this sort of "transparent" mounting was going to become a kernel feature rather than a FS.
I know the kernel has a built-in disk cache but it doesn't seem to work well with compiling. I see a 20x speed improvement when I move my source files to tmpfs. I think it's because the standard buffers are dedicated to a specific process and compiling creates and destroys thousands of processes during a build (just guessing there). It looks like I really want those files precached.....
For a beginner, which technology is best to get a break in computer networking program?cisco,Microsoft or Linux?
View 5 Replies View RelatedI had a problem with Ubuntu 10 trying to mount a non-existent directory, mount/DRIVE_F/R&RMT . It would post an error message, wait for acknowledgement (or timeout).
The only cure for this incredible annoyance was to manually create the missing directory and path.
This works, EXCEPT THAT now instead of the (Gnome) desktop coming up, the empty directory I created comes up, and I have to close or minimize it.
I can't find where in the boot process the command to mount this occurs.

I have this problem for a month now. Some apache process that appears rather slowly using 100% cpu for each core. Today I watch some logs in apache2, namely other_vhosts_access.log and discover this

On 8181 I have google sitemap generator running but I have it for over a year and it never make any problems.
I have a dummy server set up in which I am trying to install webmin (which I have done several times in the past and remb it being straightforward and pretty simple!) however when trying to install I keep getting errors.
I install all the perl packages as required :-
sudo apt-get install perl libnet-ssleay-perl openssl libauthen-pam-perl libpam-runtime libio-pty-perl libmd5-perl
After downloading webmin I try and install it:-
sudo dpkg -i webmin_ 1.530 _all.deb
This is where I encounter errors regarding apt-show-versions saying that it is not installed.I try and install it but an error appears stating that apt-show-versions is not installed. So I try and install apt-show-versions and that fails as it states that there is libapt package missing too. When I try to force install both - unable to fetch some archives but maybe run apt-get update or fix missing....It just seems like I am going around in circles (as I have run apt-get update and have run the commands as root...)
I'm playing a little bit with OpenCV but the webcam that i have on my desktop isn't app-friendly... so i could not get it working with OpenCV, it's a 0ac8:301b Z-Star Microelectronics Corp. ZC0301 WebCam and it worked out of the box with Cheese and after a little bit of tweak i get it working with camorama also.But some apps, like Skype and OpenCV demos doesn't work, believe me, i tried everything to get it working, i tried even upgrading to a very new kernel.
So i had the idea to create a "virtual" video device and using some app that can read the wcam i could print the wcam's output on such device, which should be compatible and app-friendly, so i would use that device always.
