Taylor,<div> </div><div>No one's "in charge of" the wiki; that's why it's a wiki. If people find ways to improve it, they can do so. I think your uninstalling instructions are a great thing to add to the wiki. Just hit the "Edit" button on the top left and copy'n'paste :)</div> <div> </div><div> </div><div>Jerry (re: i915.modeset),</div><div> </div><div>The legacy driver is xserver-xorg-video-intel 2.12 with the addition of the UMS code from before Karmic (so no GEM memory management, which might be causing the problems). This UMS code is what needs testing, since the X team is thinking about canning KMS for i8xx cards.</div> <div> </div><div>Now, in Lucid, KMS has been blacklisted for i8xx cards since the 2.6.32-21 kernel. So if the only change you've made is to add this aubergine PPA, then your system will boot into that UMS code. But if you've enabled any workarounds to re-enable KMS (UMS was sending a bunch of people into black screens in Lucid), or are running Maverick (which has *not* blacklisted KMS on i8xx cards), then you'll need to boot with i915.modeset=0 (or nomodeset) to get into that UMS code.</div> <div> </div><div>So if setting i915.modeset=0 does anything funky, that's a good thing to let us all know about, because that's the change that's supposed to fix everything (at least with this legacy driver). Testing i915.modeset=1 (the '1' means KMS, the '0' means UMS) doesn't help at all, because that just boots into KMS which everyone already knows is causing problems, especially with XVideo.</div> <div> </div><div>I hope that helps clear things up. So the wiki instructions aren't "wrong", it's just that the legacy driver doesn't work for you. Those are two very different things.</div><div> </div><div>-Stenten</div><div> </div><div> <div class="gmail_quote">On Wed, Aug 11, 2010 at 2:42 PM, Taylor Brown <<a href="mailto:taylor@nearlyalaugh.com">taylor@nearlyalaugh.com</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Thanks for the suggestion, Jerry. I wanted to further report that the driver doesn't work on my system whether I use i915.modeset=0, =1, or whether I omit the option entirely. At least my system only crashes after resuming from suspend... I don't know who's in charge of the wiki page, but for those users who find themselves with a broken X server it might be helpful to add a quick note about /uninstalling/ the legacy driver: 1. Login as root in recovery mode, 2. Find and remove the ppa entry in /etc/apt/sources.list.d/, # cd /etc/apt/sources.list.d/ # rm raof[something] 3. Find the newly created-added apt key and delete it and update, # apt-key list # apt-key del [whatever] # aptitude update (or apt-get update) 5. Downgrade xserver-xorg-video-intel, # aptitude remove xserver-xorg-video-intel (or apt-get remove) (choosing the option to downgrade to the earlier version) 6. Remove the modesetting line from GRUB if it's been added, # nano /etc/default/grub # update-grub 7. Exit recovery mode, login as user, and start X, # exit (log in as user) $ sudo gdm Hope this feedback helps someone, Taylor Ubuntu 10.04.1 LTS Linux 2.6.32-24-generic Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04) On 08/11/2010 06:21 AM, <a href="mailto:jerrylamos@aim.com">jerrylamos@aim.com</a> wrote: > Taylor, > > Many of us found the wiki instructions don't work.
