I have a computer with the release candidate of Windows 7 (which is now expired) that I'm intending to switch over to CentOS. Is there anything I should do(besides backing up files) before I try to install CentOS?
View 9 RepliesI'm a long time user of CentOS 5 w/KDE 3.5. I have always had this problem to various degrees no matter what installation of CentOS 5 I'm currently on. This same hardware does not exhibit the same symptoms with another OS.The problem is I regularly have many konsole instances open. I alt-tab between them frequently. Inevitably a random alt-tab will freeze the keyboard and the mouse won't be able to click anything although I can move the mouse cursor around. I can't type anything. It seems to have some sort of timeout and it always come back to responsiveness.
I alleviated this problem (I think) by switching keyboards, installing the nvidia driver instead of the nv driver, shutting down all non-essential services.I have seen these symptoms on every system I have installed CentOS 5 where KDE 3.5 was also installed. Very different hardware setups each time.Has anyone else run into similar symptoms?I'm surprised that it's just CentOS 5 w/KDE 3.5 that exhibits this behaviour on the same hardware where other operating systems (gentoo, suse, etc.) did not exhibit these symptoms.
In Fedora 11 I cannot switch keyboard layouts between English-Russian-Ukrainian when using window managers other than Gnome/Metacity/Openbox. However, I can see my custom "us,ru,ua" layout in GDM. My "/etc/hal/fdi/policy/10-keymap.fdi" file is as follows:
Code:
<?xml version="1.0" encoding="ISO-8859-1"?> <!-- -*- SGML -*- -->
<deviceinfo version="0.2">
<device>
<match key="info.capabilities" contains="input.keymap">
<append key="info.callouts.add" type="strlist">hal-setup-keymap</append>
</match>
<match key="info.capabilities" contains="input.keys">
<merge key="input.xkb.rules" type="string">base</merge>
<!-- If we're using Linux, we use evdev by default (falling back to keyboard otherwise). -->
<merge key="input.xkb.model" type="string">keyboard</merge>
<match key="/org/freedesktop/Hal/devices/computer:system.kernel.name" string="Linux">
<merge key="input.xkb.model" type="string">evdev</merge>
</match>
<merge key="input.xkb.layout" type="string">us,ru,ua</merge>
<!-- <merge key="input.xkb.variant" type="string">,,winkeys</merge> -->
<merge key="input.xkb.options" type="string">grp:ctrl_shift_toggle,grp_led:scroll</merge>
</match>
</device>
</deviceinfo>
The file "/etc/sysconfig/keyboard" is
Code:
KEYBOARDTYPE="pc"
KEYTABLE="ru-cs"
LAYOUT="us,ru,ua"
MODEL="pc105+inet"
OPTIONS="grp:ctrl_shift_toggle,grp_led:scroll"
VARIANT=""
Does this problem persist in Fedora 12?
I'm switching over to Ubuntu 10.04.1 from Windows 7. I mostly use my computer for surfing the web and doing school assignments, but I'm sick of getting viruses and such on Windows 7.

View 1 Replies View RelatedI'm using 11.04 with Gnome 3 and it seems I can't change windows by using alt+tab. Is this a bug or a feature?
View 4 Replies View RelatedI was running 11.04 as my main OS untill I installed Win Xp Pro. 50 GiB Ubuntu and 100 GiB Win Xp Pro. Now when ever I boot my computer (Acer Extensa 5620) it AUTOMATICALLY goes into the Win Xp Pro OS. So I have no idea how to access all of my Ubuntu files and programs etc. This is a really big problem as I have yet to hook up Win Xp Pro to the internet. It is an older OS and it has made things very difficult. So I really need to be able to switch OS partitions.
View 4 Replies View RelatedI'm contemplating to switch from sendmail to postfix. My current setup is very simple: a minimal CentOS 5.5 64bits install with Selinux enabled on ports 25, 80, secret sshd, 53 and 953. I also use Google Apps for my domain to manage the email accounts. Basically, I use sendmail only to email the daily logwatch, as well the email sent from my forum software. The issue that I'm facing is the forum is starting to hammer sendmail with a lot of emails.
My goal is to use Postfix only to send those forum emails. I don't need a SMTP setup, that is handled by Google Apps. Can I do that with Postfix? Will Postfix perform better than sendmail? All guides I saw on internet pair Postfix with Dovecot and the setup is a little complex, not to mention that I will never have email accounts created on server.
I was wondering if you have any handy guide who will basically replace sendmail with Postfix. Personally, I tried myself using the CentOS HowTo. I yum'ed postfix and system-switch-mail, then I disabled sendmail and switched the agent to Postfix. I left the main.cf config unchanged and tried to start Postfix (service postfix start), but I got a "master is stopped" message when I checked the daemon status.
Im using xfce desktop environment in debian. I find that I can not see the desktop when using Ctrl+Alt+Tab to switch window focus. I modified /usr/share/xfce-mcs-plugins/shortcuts/defaults.xml and added Ctrl+Alt+Tab shortcut to trigger a terminal command "wmctrl -k on", then i could see the desktop, but failed to switch window focus. Also, I failed to solve this problem by editing /usr/share/themes/Default/xfwm4/keythemerc Could anybody tell me a solution that you should be able to see the desktop when switching window focus, just like in win7?
View 8 Replies View RelatedI'm currently running a Vista machine, but would like to switch over to Linux, Ubuntu in particular. My question is can I switch over to Ubuntu, keep my Windows partition and use VirtualBox to access the pre-existing Windows partition? Or does VirtualBox require me to create a new install for Guest operating systems?
If not, are there any other free alternatives to accomplish this?
I have Googled a bunch for this and have found that it may not be possible, but I would love to find out I am wrong since this is the issue keeping me from switching from Windows full time. My school uses an Exchange server hosted by Microsoft and accessible, from Outlook 2007 through Outlook.com via http proxy. We have laptops with MS office 2007 installed and can use the Outlook connector to connect to this server.Is it possible to use an email client in Linux to connect to this server and retain the use of mail and calendar.

I am switching from Windows Server 2003 to Ubuntu 11.04.
These are two different machines, the Windows Server has 2 2TB Hard drives in it, that are setup as a RAID 1. The data on the drives is irreplaceable. I've scoured the internet for about two weeks, trying to find the best solution. It seems like everyone else had a slightly different setup, or the was no solution.
The Ubuntu Server has a 40GB SSD in it. I just installed a 2TB Hard drive (same make and model of the two in the Windows Server) and made the filesystem for it ext3.
First thing I did was just throw the 2 2TB Hard Drives in the new server, and tried to set them up as a software RAID. After it prompt me to erase the drives, I strayed away from that idea.
My end goal is having Ubuntu machine completely replace the Windows machine, so I'll need to setup Samba (which I'm sure I can figure that part out).
How can I get all the data off the 2TB Hard Drives that are using NTFS onto a RAID in the Ubuntu machine with an ext3 filesystem?
I just installed PHP 5.2 using this guide [url]
The install did work without errors and is listed correctly on yum but isn't working when I test a php script.
So now I need to downgrade back to the php 5.1 but yum is now stuck on this atomic repository, how do I get back to the Centos repository and downgrade PHP to 5.1?

I've switched from Ubuntu Hardy to Xubuntu using the terminal. The only problem is I can't find my WinXP partition any more. In Ubuntu I used to mount it by going to 'Places' menu and clicking the folder icon. It's now gone. I can't see the icon in Xubuntu.Been reading other threads trying to find out what to do, but I'm relatively new to Linux. I can't find the folder under /media either. Also, I don't know what types my partitions are. Is this important? I figured I could access my Win folder in Xubuntu the way I would in Ubuntu.
View 4 Replies View RelatedI am using Linux and Windows 7 on the same machine and my on-board NIC is functional under both. However, the weirdest thing happens when I browse the internet under Linux and then return to Windows; my NIC stops being recognized! This happens under Windows but also in Linux when I return! This problem is then easily fixed by resetting the CMOS, but inevitably occurs again. Why does this happen? Update The CMOS reset works but is not necessary for me. Shutting down and unplugging the power cord works as well.

View 5 Replies View RelatedI just switched from Windows to Linux. I've been using EditPlus for many years mainly because of it's ability to save locally, and then send the file via FTP, with easy keyboard shortcuts (ctrl-s to save, ctrl-alt-s to ftp).
I also need syntax highlighting and basic code editing features. Is there anything for Linux that can do this? I don't want to run EditPlus via Wine
I need to save locally and remotely simultaneously, or at least with a few keystrokes. I already know of plenty of ways to edit remote files.
I am currently dual booting between Linux Mint 10, and Windows Vista SP2. Wireless works fine in both these OSes, but when I quit Mint and load Windows, 70% of the time my wireless stops working.
ie, it does not detect any wireless networks nearby, althought there are tons of them.
Restarting the wireless device doesnt help, I have to restart my computer at least 4 times for wireless to start working again.
And as of now, my wireless in Linux Mint has stopped working.
My Sempron LE-1100 home server (1GB RAM) has run CentOS 5 32-bit happily for years, but I decided to replace its two Seagate 250GB drives (RAID1) with two WD 500GB black drives (RAID1). I decided to do a fresh install and used CentOS 5.5 64-bit this time. Since switching to the 64-bit OS with the new drives, my transfer speed across the LAN has dropped from a reliable 45MB/s to only 18MB/s from other machines to the server, and to 27MB/s from the server to other machines on the LAN. I use gFTP or WinSCP for these transfers (in FTP mode). Prior to installing the new WD drives, I ran the long WD tests on them and they passed, so I don't believe the drives are faulty. I suspect it's more to do with me switching CentOS from i386 to x86_64.
I've got two questions:
1. Is the 64-bit version of CentOS appropriate for a Sempron LE-1100 with 1GB ram, or should I switch back to the i386 version?
2. Is there a reason why switching to the 64-bit OS would negatively impact on transfer speeds? I doubt the new HDDs are faulty...I was expecting them to be faster.
3. Is there anything I can try to improve transfer speeds across the LAN?
