PAE kernel breaks NVidia Drivers (Ubuntu)

Thursday, May 19th, 2011

I’m running on a ThinkPad T410 with 4GB RAM. I need to stay on 32-bit as I have some dependency on 32-bit applications that I couldn’t get running on 64-bit. Thus I’ve installed the PAE kernel to access all the RAM. Problem is, this broke the graphics.

After booting up the first time, I was presented with the option of running Ubuntu in low graphics mode – great.

Anyway, the fix is nice and quick. Go into the Hardware Drivers tool and disable the NVidia driver. Reboot – you should now be back to normal resolution, just no acceleration. Re-enable the NVidia drivers and reboot again and everything should be back to normal.

HTC Incredible S, internet over Wifi not working

Saturday, May 14th, 2011

After recently buying an HTC Incredible S, one of the first requirements was to get it connected to the home Wifi. For security I use WPA-PSK and also MAC address filtering. After adding the MAC address to the router and configuring the password, the phone connected to the Wifi with no issues. But after trying to use the market and the internet it was apparent that the connection wasn’t working.

After a little bit of troubleshooting, I discovered I could actually access other computers on the home network, but could not access anything on the internet. This didn’t seem to be a DNS issue as using straight IP addresses didn’t help either. After reading a few posts, it seemed this might be an issue with my SpeedTouch router (and/or the combination of the SpeedTouch with an Android 2.2 device).

Anyway, the current solution (or workaround) is to use a static IP address on the home network. Once configured, everything works as expected. But, this is a workaround, and I wouldn’t want to have to do this on other Wifi networks (which I’m yet to test).
