This has been an ongoing issue with X11 compositers like marco, unity and cinnamon etc... Ifind especially with an Nvidia GPU that as the system runs longer after a number of weeks or a number of months the GUI just gets slower and slower. It's not something you'll instantly notice but just a hint of lag here or there that gets worse. One hint you'll find is by watching nvidia-smi and checking the utilization you will start seeing random spikes of 80-100% even without maxi........

If your audio is not working and you got this in your syslog: pulseaudio[13710]: [pulseaudio] sink-input.c: Failed to create sink input: too many inputs per sink. The issue is generally caused by too many audio inputs, or in other words you have too many applications that are hooked into pulseaudio. An easy and notorious offender is by having dozens of Firefox browser tabs open. Solution: Close all of your Firefox and the problem will........

Here's a proven example of what a bad hard drive can do, it was technically functioning OKin a RAID array but the system became extremely low and the load become high and IOWAIT was even higher and I always thought it was a bad application. The truth is that this failing 1TBHitachi has slowly gotten worse and caused huge slowdowns, (eg. 100% load on Thunderbird waiting for e-mails to load etc..). After swapping it out, tabs change instantly, emails are not lagged, and........

I've used rsync again for this because I found it very simple, I've only excluded the Cache directory since it's not necessary and could be several GB in size. rsync -Phaz --exclude=Cache/* user@remotehost.com:/home/user/.mozilla/firefox/profile.default/* /home/user/.mozilla/firefox/ec1n9opl.default/ This is a great way once again to get going how you were on the old/remote computer fairly quickly. It even restores all of your history in........

After about 15 tabs I believe, they become hidden on the right side and are accessible only by furiously clicking the "right arrow" and even then it takes forever and honestly this hidden tab feature seems to slow down everything. If you enter "about:config" in your browser without the quotes just set this value to get rid of this annoying (one of many new) feature from Firefox (set it to false and restart your browser): services.sync.prefs.sync.brows........

Type "about:config" in your browser and then search for "Quit" Set these values to true browser.showQuitWarning browser.warnOnQuit........

yum exits in the middle The problem is this VPS seems to be an OpenVZ template from HyperVM. The only way to make it work was to disable i386 packages since this was an x64 kernel. That shouldn't be necessary but it was the only way to make yum stop quitting after the first package or two. I couldn't find any issue by checking the logs either. echo y|yum install vim-minimal telnet expect jwhois net-tools slocate iptables elinks gawk L........
