Is there an entry in System->Preferences that corresponds to the session preferences in older Fedoras? In particular is there a way to save the current session so the same programs open up when I log-in again?
View 1 Repliesi need to build a pc, that allow to everyone to use it, and that does not "save" nothing (a guest volatile session)
i see the xguest package, looks good, but has 2 big problems:
1) seems not possible to customize the session (eg: modifying the home), and this one is not so a big one
2) is impossible to choose a localization: with the fedora login screen it is possible to choose the localization only after clicking on thje usernname, but using xguest, if i click on the username starts promptly the session
so i'd like to ask if is there any workaround for have that "volatile" and better if customizable home i thinked , IF possible to copy an home folder to /tmp (if possible and use the /tmp instead the home during the session, obv with enough available ram) OR copy a home from a user to the"GUEST" one at the start (boot, or login), then delete it at logout or turning off the pc
I have a few questions related to the 'Save Session for Future Login' option you can check (and is checked by default) when you go to shutdown/restart/etc.
1) What exactly does checking this option and shutdown/restarting do?
2) Is there any way to have it unchecked by default?
3) Is there any way to completely remove the option?
I haven't installed ubuntu but using it from my Pen drive. The major problem I am facing is I am not able to save my current session. For example I will download and install a couple of software like 'WINE', 'java plugin' and other useful software for me, but when I shutdown everything is lost and I get a new copy of OS on my next start-up.I can't install a copy ubuntu on my hard disk as I have only single partition on which windows is running.

Is it possible to restore previous session using bash script when fluxbox starts?
after the upgrade to maverick, gnome-session-save doesn't save applications on shutdown or logout as it did on Lucid.I've noticed the following things:
On Lucid, if I had a stopped job in a shell, the system refused to logout or shutdown, showing a confirmation window. On Maverick, the CPU goes to 100% and then the computer shuts down; on reboot, no application is saved
On Maverick, if there are NO stopped jobs in a shell, I can logout cleanly but only a few applications are saved (eg. terminal, firefox) but others aren't (eg. empathy,evolution) I've checked "Automatically remember application on exit" in "Session management" menu.
I used to use kubuntu last years, but I decide to give Ubuntu a try instead.A thing that was working on kubuntu's KDE by default, is that when you close your session, the system remembers what applications was you using, so in the next boot up they will be open exactly as it was.I would like to have this feature also on my Ubuntu 10.04, but I've been not lucky searching for the option to enable it.

I'm running Karmic 64-bit and Kate 3.3.90.I have been splitting up a very large (16,000 lines) text file by copy/pasting bits of it into smaller files. I had about 40 of these smaller files loaded into a session along with the large file. About 20 were from a previous day of editing and about 20 had been added (and saved) today.
I tried to save the file I currently had open and Kate crashed. I didn't think it was that big a deal until I reopened Kate and all of the files I had added today were gone!!I've looked in the folder and even the backup files that should have been there for files I'd saved more than once are not there.
I have created a virtual machine of a system running Fedora Core 4 and I need to upgrade it to Fedora Core 10. Based on what I have read, it iis possible so I started theupgrade process. I get an error message saying that /dev/hda6 (my root paritition does not exist) even though it does.
Does the installer need to read a label from /etc/fstab? I executed tune2fs -L / /dev/hda6 amd ,and added LABEL=/ for the corresponding entry for fstab. but the FEDORA CORE 10 is still giving the same problems for the installation process. Should I upgrade to an intermediate verson like Fedora Core 7 first?
I am in school for my CIS degree and the book I am using this session covers Windows XP and Fedora Core 4. I am having trouble finding & downloading Fedora Core 4. My question is: Is there a big enough difference between Fedora Core 4 and Fedora Core 14 that I would not be able to use 14 instead of 4?

View 6 Replies View RelatedI have a command line OCR program called OCR Shop XTR (Vividata corp) that I am using on a system with a 6-core AMD chip. I changed the bios so that the 6-cores were activated, but htop shows me that while the program is running, I am only getting activity on one core (the program maxes out the one core with consistent usage between 97% and 100%).
I have read that many programs are not written to take advantage of multiple core cpu's. However, I am just hoping that there is some way to get this program to take advantage of the extra cores. Does anyone know of a way to invoke programs from the command line which would spread the workload out among additional cores?

Just a quick question. Does Kubuntu Karmic support core 2 E8500 out of the box or do you need the SMP kernel?

View 2 Replies View RelatedI have now installed Wheezy on two different hard drives and in each case it seems only one CPU of my dual core CPU computer is recognized. System Monitor, Gkrellm and lscpu show just one when prior to the new install the old Wheezy showed both CPU's. I have put the hard drive into two other computers with dual core CPU's and all show just one CPU.
Interestingly System Profiler and Benchmark (hardinfo?) > Devices > Processors now show a large amount of processor infomation when with the old Wheezy I would only see both CPU's listed and nothing else.

I recently read in a forum that by default the Linux kernel only activates one of two cores in a dual core processor. Searching online gave one option to find out and that was the mpstat command. I therefore ran the command and got the following output.As the result says, it shows only 1 cpu. I was wondering what I could do to activate both cores in my machine, and whether doing so was going to cause me any problems.

View 5 Replies View RelatedI've a program that launches new processes, and wait for them to die before it exits. So, for example, my program is a process, and it launches 3 more processes, and when the 3 child processes end, it will exit.
As you see, at end of the example, the program used a total number of 4 processes.
1 - Now, I'm running this program in a CPU with 4 cores. This means that the program used each core for each process?
2 - How can I know which core the program used?
I want to generate core dump files from my program when it crashes. Its a pretty big process and has about 10-11 threads in it.I have followed the documentation to enable core dump by setting ulimit to unlimited etc. I quickly tried "A demo program creating a core dump" from the following webpage, which succeeds in Segfault and dumping a core file in the directory that I configured.However, I tried running my original program and caused it to crash. I did this by making calls to kill(), raise() or the same null pointer access as shown in the webpage above. In each case, my program crashed but did not generate a core dump file. Am I missing something?My program is in C++ and my environment is Redhat 9.0 (kernel 2.4.20)
Going through the "Why do I NOT get a core dump?" section on the same webpage as above, I can see two potential problems. One - there are issues with the suid/sgid (bullet # 6). I am not able to change any settings with suid because my system does not contain either /proc/sys/fs/suid_dumpable or /proc/sys/kernel/suid_dumpableTwo, my program has threads in it and the bullet # 8 is the problem.
We have a small cluster of 20 HP systems, all running CentOS 5.3 in an NFS-root environment. Half are quad-socket, quad-core Xeon E7340 @ 2.40GHz (total 16 cores), the other half are 8-socket, quad-core Opteron 8354 (total 32 cores). All systems have a Mellanox Infiniband adapter ("Mellanox Technologies MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE] (rev a0)")
With kernel 2.6.18-128.1.6.el5, infiniband works fine on all systems.
With the update to kernel 2.6.18-164.11.1.el5 (and both types of node running the same NFS-root image), the 16-core Xeons still work fine. Infiniband no longer works on the 32-core Opterons. Specifically, either the ib0 interface fails to appear, or it does appear but when configured with an IP address, doesn't actually work. In either case, loading the IB kernel modules takes a long time, but I haven't instrumented the load script yet to see which module, if any, is at fault. More errors listed below.
However, if I tweak the BIOS of the 32-core systems to reduce the per-socket core count to 2 (so effectively 8-socket, dual-core, down to a total of 16 available cores), Infiniband starts working again. Putting it back to 32-cores makes it fail. Booting the older kernel makes it work again. In summary: old kernel, IB works on all systems. Newer kernel, IB only works on 16-core systems.
Updating the IB firmware from 2.5.0 to 2.7.0 (latest available) doesn't help. I also did a full 'yum update' to make sure that libmlx4, openibd all other associated packages were up-to-date. Doesn't help either.
Some errors that appear on 32-core nodes:
ib_query_port failed (-16) for mlx4_0
ib_query_port failed (-16) for mlx4_0
mlx4_core 0000:04:00.0: SW2HW_MPT failed (-16)

View 4 Replies View RelatedI have a very bad attempt at hashing the components of an tcp session to assign/locate the session in a hash table bucket. I am pretty sure that it has a very high collision rate and when there are a very large number of tcp sessions my application is having to search a long linked list to find the session within the bucket.
All the hashing functions I have found take a single string input where I need to input several integers and hash them into a single result. My guess is that any real hashing function is going to produce better results than what I am currently doing.

I did a horrible mistake due to lapse in my concentration. Here is the 80 GB IDE disk geometry:
=> C: Windows XP SP2 15 GB partition
=> D: NTFS parition - 10 GB
=> E:F:G:H: NTFS partitions on the Windows Extended partition.
=> On the same Extended partition, there exists Linux /swap and /root partitions.
What happened was:
a) I wanted to delete the H: parition which was residing adjacent to Linux partition
b) By mistake I opened the Explorer and clicked the Mouse on H: partition and left it like that (forgot)
c) I opened Add/Remove program list but did nothing, to do few uninstalls after partition deletion.
d) Now I opened compmgmt.msc for Disk Management then deleted the H: partition!
Then XP reacted strangely and got almost hung
e) Then I switched OFF and ON the PC.
f) Most shocking was GRUB screen vanished (crash console appears) which means that Linux partition got deleted instead of H: partition!!
It's important to share with you that Fedora Core 12 possess the default BOOT flag. I thought that it's nothing big deal, only a case of Boot flag toggle with DOS bootable CD but am shell shocked to find after hitting the fdisk from DOS it says Error reading the disk!!! I felt like collapsed for a while, don't know how I did such a mistake. how to boot into my Windows XP. I can't afford to loose data or bear the expense on Data recovery
