Since I first bought my Logitech MX5000 combo it has never worked correctly on Ubuntu (back to 6.06 maybe…) after booting. The keyboard would work perfectly in the BIOS and even in GRUB, but as soon as I reached the (GUI) log-in screen my MX5000 would become unresponsive until I disconnected the USB Bluetooth receiver and plugged it back in. As you could imagine, quite tedious on every boot.

After doing a bit of research, this appears to be a fairly common issue. One suggestion that did work for me was to remove the bluez-* packages, but apparently there is the side effect of other Bluetooth devices no longer working. This isn’t an issue for me, so it’ll keep me happy until a real fix is in place.

Drop the following into your CLI if you’re having the same issue…
sudo apt-get remove bluez-cups bluez-pcmcia-support bluez-pin bluez-utils

Ever since the upgrade from 7.04 to 7.10 I have been experiencing random crashes. The type of crash varied from full-on lock-up where the only way out was to hit the reset button to mild crashes that could be escaped by restarting X (Ctrl-Alt-Backspace). Sometimes the system would just hang for 30 seconds then come back to life.

As you could imagine this was becoming rather irritating, it being my main dev-box and all! I started monitoring my system from another machine on my desk over SSH by running top. It would appear that whenever my machine ‘crashed’ Xorg would be the culprit, consuming 100% of my processors cycles.

It turns out that many people were experiencing this problem over at the Ubuntu forums and there seemed to be a trend developing where a large proportion of us were using 64-bit AMD X2 chips and the Nvidia GeForce 7 series cards, namely the 7300. My fix involved downgrading my video drivers from the proprietary 100.14.19 to the 100.14.09 release, obtainable from the Nvidia website. This fix didn’t work for everyone in the thread at UbuntuForums, but did for some.
