Eduardo: Please be aware that pre-released updates have a slight possibility of not working well (that's why they're PRE release, after all).
Your safest bet, if it's not 100% vital for you to have the hibernate functionality right now, is to wait until the 2.6.38-9 kernel makes it into official updates, when that happens, update manager will automatically offer to install it for you. It should only be a few days. That said, if you want to try your hand at pre-released updates: 1- Go into software center (it has an icon on the Unity panel, on the left side). 2- On the menu, go to Edit -> Software Sources. 3- On the Updates tab, check "Pre-released updates (natty-proposed)". 4- Close the software sources dialog, let software center perform its update process, it will tell you when it's finished. 5- Launch Update Manager. 6- I strongly suggest you uncheck all the updates EXCEPT for the linux-image ones which will install the 2.6.38-9 kernel. 7- Go through the update, restart the system if desired. 8- Once you're up and running with the new kernel, I recommend you disable the pre-released updates by following steps 1-3 and UNchecking natty-proposed. Unless you have a specific reason to want pre-release stuff, it's safer to do it this way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745304 Title: Graphics corruption after hibernate with Intel GMA 3150 chipset -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
