I recently purchased an Acer C7 and installed ChrUbuntu 12.04 on it successfully. The laptop so far is fitting my needs (something cheap to carry to labs/read PDFs and email with) but it's pretty sluggish at times. Are there any tweaks to speed it up a bit, allow 720p to be more playable, etc? I've read Lubuntu and Xubuntu are built for lower end hardware, is it possible to install that?
Thanks
