I just installed ubuntu 10.04.02 on to my tablet, aside from the dreaded intel video problem. Install went ok, but I'm finding now. That when I rotate the screen, the touch screen isn't adjusting to match. I'm not really ubuntu savvy.
View 6 RepliesI have a slight problem with setting of a stylus in my Tecra m7. It works fine when screen is in default position, but when I rotate the screen to vertical (left/CCW) touchpad and stylus input does not change so when I move it up it it goes right ^^'
xinput goes like this:

I already tried few .sh's from this forum archives but it didn't seem to work. I disabled driver for graphic card, because recommended version showed only violet screen when starting system and older version does not support rotation. I use Ubuntu 10.10 with Gnome.
I have a big LCD screen.I make it 90 degrees retated to play games .But I want to know :if I can get rotation in boot up? I'm using Fedora 12 in KDE. My screen display driver is Intel . I think can write something into /etc/X11/xorg.conf to make it,or write into KDE's init script /usr/bin/startkde ( if there is a command like"rotate 90",then I can write it here).
View 3 Replies View RelatedI have an HP Pavilion tx2000 tablet, wich is working perfectly in Ubuntu 10.04. The touch and the stylus works out of box, and i'm using the script that Favux has posted to rotate my screen and i've installed the wacomrotate daemon, wich is working too. Now, I've two questions: How to calibrate it? The stylus is ok, but the touch isn't calibrated. In Karmic, I was using wacomcpl and xsetwacom, but neither of them detect my tablet now (in 9.10, Hal was used to detect the tablet, now it's xserver-xorg-input-wacom).

It's possible to set up the automatic screen rotation, like in Windows (the screen rotates automaticaly in tablet position)?
Recently installed ubuntu on my gateway m275 tablet alongside windows xp tablet. Everything, including the stylus/pen without any poking around. However, I'm having trouble getting the screen orientation to rotate.
If I go to system-preferences-monitors, the only option for rotation is "normal".
Here is my xorg.conf:

I installed 8.04 ubuntu on my Dell Inspiron 9400 laptop. I upgraded it to 10.04. My screen now has a terrible wave on it when I scroll up or down.
View 3 Replies View RelatedI just replaced my older monitor with a slightly newer, much nicer Dell 1905FP. I need to have it rotated, but I have no clue how to rotate it. I have seen several xorg.conf modifications that are supposed to work for some of the nvidia drivers, but nothing for the generic radeon driver. The radio buttons in SaX2 are grayed out as well. How do I set up X11 to rotate my display? Preferably without installing the other ATi driver, as I have tried before to switch to that one, and have been unsucessfull.
View 5 Replies View RelatedOn my Windoze machine, I use Replay Media Catcher 4 which runs silently in the background and captures any videos (FLV, AVI, MPG, WMV, etc) on any websites that I happen to go to, and saves them to a folder on my hard drive. Right now, if I want to save a video that I'm wathing from Ubuntu, I have to go to /temp, guess which file it is, and copy it after it downloads fully but before it finishes playing, otherwise Firefox deletes it from /temp right away. This is a pain.
Yes, there are screen motion capture utilities in the Ubuntu Software Center, but they're just screen scrapers that result in low quality copies without any audio. I want something that will actually capture the video stream and save it as a file. Even if it doesn't save all videos automatically like RMC4, and I have to right click on the video to Save As, that would be better than copying it from /temp at the precise exact moment.
after i have installed suse 11.4 on my acer m1300 my computer (desktop) won't auto boot. if i boot it manually my computer freezes. only if i boot it in revovery mode it continues with automatic confiration and it installs suse. but even than it won't reboot and i have to shutdown the hard way. when i restart the computer freezes and won't open opensuse.

I was asked to research if it is possible to install a Debian distribution of Linux to HP Z420 Workstations as second OS (dual boot) in our lab. The lab is normally used for Computer Aided Design (Windows 7). The plan is to have parallel computing possible with these workstations on Linux side.
The link for HP Z420 Specs suggests amd64 distrubition should be supported. Tell me If I'm wrong as I have always been interested in software side of things.
Looking for info regarding installation of Debian to HP Z420 workstations as well as using these computers for parallel computing with Debian.

View 6 Replies View RelatedI want to set up a cluster for scientific computing (mainly statistical stuff with R). I have a few conceptual questions. First, is there a difference between a Beowulf cluster and a cluster that has single-system image ("SSI," e.g. using openSSI or LinuxPMI)? If so, what's the difference? Second, if there is a difference between Beowulf and SSI, which one is better for scientific computing? Third, does using Eucalyptus make sense for scientific computing or is this more suitable for IO-oriented operations such as web service or databases
View 2 Replies View RelatedI have a plan to deploy a private or public cloud computing. And I've been considering Eucalyptus, OpenNebula, Nimbus, vSphere, abiCloud and Joyent.
I'm very interested in Eucalyptus and OpenNebula, since they are both open source, they have many features, they both support Amazon EC2 and Amazon APIs and they seem to be able to work with different hypervisors, such as KVM, Xen, VMWare ESXi, etc.
Eucalyptus seem to be very supported by Canonical, because it can work with Centos Server, so I bet it will grow more and more, and we have a good experience with Linux and in particular redhat.
On the other hand, many people told me that right now OpenNebula is better. So the question is:
- which one between Eucalyptus and OpenNebula? The other three choices? vSphere is probably free (if we use ESXi and not ESX) but it's not open... abiCloud seems to be similar to Eucalyptus and OpenNebula... about Joyent, many people say very good things, but I want to know more, and then, is it open source? I mean here, can I use it as free ?
After having built the private cloud, we probably want to also use an external service and create an hybrid cloud. If for private cloud we chose OpenNebula,Eucalyptus, abiCloud or Nimbus I guess the best thing is to use Amazon EC2.
- Is it also possible to use VMWare solution?
- And if we chose abiCloud or Joyent, what can we use to create an hybrid cloud?
About Microsoft Azure and Google App Engine, it seems to me they have many limitations and I prevent it because it could be have a highly cost, so I'm not considering them.
I have up graded to natty 11.04 and am trying to get magick rotation 1.4 working on my hp tx2000 model 2130ea.I have spent a lot of time reading the forums and trying stuff including breaking natty a few times and had ton do a reinstall. Anyway I am not to sure what I am doing wrong missing a script or something I have tried a few different ways to try and rotate screen at the moment I have magick rotation installed and the only thing I can do with it is turn on/off touch and if I move the courser over the green arrow icon a drop down box appears saying its loading. I did turn on the bug report and this is what it says I attached the log.

I have also tried putting the path to the file /etc/logrotate.d/rsyslog. Restarted services and still no logrotation for the ldap.log..
I have a Linux program which can write information to stdout and stderr.
I have a shell script which redirects that output to a file in /var/log. (Via >> and 2>&1.)
Is there a way to make that log file rotate? (max size, then switch to a different file, keep only a limited number of files)
I've seen a few answers which talk about the logrotate program, which sounds good, but they also seem to be focused on programs which are generating log files internally and handle HUP signals. Is there a way to make this work with a basic output redirection script?
I can't forward my kerberos credentials to a computing resource before connecting to the resource for which I have kerberos credentials. In other words, from my machine at work I obtain my ticket with kinit -f to a computing facility off in some lab somewhere.
Then, I want to ssh to another machine in another department (I don't have control over the krb5.conf file or this would have been easy) where I work. It is on this machine I want to be able to ssh,scp, etc to this far off lab. I've tried several options around this barrier, but I'm a total failure thus far. I checked that GSSAPIAuthentication is set to yes.

i can handle basics but once i get into coding it confuses me. i downloaded motion and webcam-server onto my other computer on the local network, but all i really want to do is access a live feed from my main box and be able to record a video if need be, for security purposes (we had a break-in awhile back). after starting motion, it saved a few .jpgs to the tmp folder, then i shut it down and restarted it as a test, now it's not even doing that, i'll post the readout of what it spat out in a minute. how do i (1) disable the .jpg saving feature, (2) enable video recording, (3) run it in the background (as a daemon?) without the terminal window being visible onscreen, and (4) access it on the main box? also, i couldn't seem to edit the motion.conf file even though i'm an administrator.

I have recently done a clean install of Lucid Lynx and set everything up the way I had it in Jaunty (skipped Karmic). However, I am now having problems with the Compiz Cube and Firefox 3.6.
Whenever I rotate my workspace that contains a Firefox window that is active, the animation is very jerky and slow. It is fine if Firefox is a background window. This was never a problem in Jaunty with Firefox 3.0.
Is anyone else having this problem? Does anyone know how I might be able to fix it? I have tried disabling all addons in Firefox.
My PC: Core 2 Duo E7400, Geforce 7010 (onboard), 2GB RAM
UPDATE: starting Firefox in Safe Mode seems to help a little. Not sure why though...
I am running Kubuntu 10.10 x64, using a Wacom Bamboo (CTH-460), I installed it by compiling the driver and moving the file as in every tutorial I could find in the Internet. The pen works perfectly, except by the fact I use TwinView and the tablet uses all the width, too sensitive. but this is something I plan to fix later... (pressure is OK)
the problem is the touch.. It almost works, right click, zoom and scroll support is ok, I believe there is no support to rotation but I can live without it... The problem is the cursor movement, seems to be a sensitivity issue. If I move very slow there is no problem, but if i move a little faster the cursor stops as if I had removed the finger from the sensor. When I try to scroll or zoom I have a similar problem, it moves an inch before it start to scroll as if it wasn't sensing the second finger, but right click is perfect so I don't think this is the problem.
Would this be a bug? Is there a way to calibrate the touch sensor? I remember editing the xorg.conf to make the touch fit the screen size in a HP Tx2510us, and to make two finger scroll on to touch pad but it was in 8.10 I believe, I cant find something like it for this problem. wacomcpl cant see the device, xsetwacom list returns nothing... xinput list returns this:
