hey there.I have an acer ao751h with the poulsbo chipset that runs ubuntu10.10.I had everything configured and working but i did a kernel update and now i my X doesn't work.I thought that i could try the new kernel and in case that it didn't work out i could just switch to the other one.I need to "cancel" the update i did and reverse it.How can i do that via the command line?Also does a kernel update in ubuntu autoremove the previous versions?
thanks
