I think I've fixed my Ubuntu 8.04 screen/keyboard/mouse-freeze issue ... but should I upgrade to 8.10?

Every time I write about Ubuntu 8.04 LTS, which I've been running on my Gateway Solo 1450 laptop since its release in April, I mention that it's the only GNU/Linux distribution I've used that successfully suspends and resume the computer.

And I've made that feature — suspend and resume — the bar over which other distros must jump to "beat" 8.04 on this platform.

Make no mistake, I've "enjoyed" a working suspend/resume capability. But I haven't enjoyed returning to the laptop after a while to find the screen looking normal but the keyboard and mouse completely dead. CTRL-ALT-backspace won't kill X. CTRL-ALT-delete won't reboot the machine. I need to do a hard boot with the power button to get things working again.

I've had X issues in many distros, most severely with Debian Lenny, my preferred distro for this PC, which has serious problems with refreshing the screen, leaving the upper panel in GNOME and many graphical elements of various applications virtually unrecognizable after about a half-hour of use.

I appeared to have a similar X issue in Slackware 12, which I installed only briefly (and too briefly to make a determination, especially since I never got a "perfect" X configuration), but other systems, including CentOS 5, Fedora 9, and Puppy 3.00 had none of these issues.

Nor did Ubuntu 8.04, which automatically wrote an xorg.conf that was much different — being way more spares — than any other I'd seen before. But X performs flawlessly.

Even though suspend/resume works in Ubuntu, I'm now about 80 percent sure my intermittent keyboard/mouse freezesare caused by whatever daemon is responsible for automatically checking whether or not to suspend the system.

I pretty much arrived at this point through the process of elimination with the addition of a little bit of logic. Since no other distro appeared to be freezing like this, and since I only have automatic suspend/resume set on Ubuntu, that seemed to be the most likely cause.

So I went into the GNOME Power Manager utility and turned off the "put the computer to sleep after XX minutes" feature.

Since then, I've had no freezing whatsoever in Ubuntu 8.04. A month from now, I'll be sure.

Unfortunately, I haven't been able to figure out the problem with screen refresh in Debian Lenny. I'm considering wiping it from the laptop and trying another secondary distro, maybe CentOS or Fedora. Even Sidux — a more "tame" version Debian Sid — is something to try just to see if I continue to have the screen issues.

Or I could just stick with Ubuntu 8.04. I'm not thinking about upgrading to 8.10, which not coincidentally is available for download today.

Click that last link to see the major new features in Ubuntu 8.10. I'm very unlikely to need 3G wireless, but if I find that 8.10 supports my Airlink 101 AWLL 3028 USB wireless adapter, I would strongly consider doing the upgrade.

I'm sure all of the Ubuntu mirrors are straining mightily with everybody trying to download the whole 8.10 image or upgrading their current installations. I'll be waiting at least a couple of weeks before I try to download the ISO and burn a live CD. If that loads and then the wireless works out of the box (I won't be holding my breath), I'll go forward.

Otherwise, I'll stick with 8.04 LTS — the long-term-support edition of Ubuntu that will be supported until 2011 on the desktop.

But with suspend/resume off the table, Ubuntu has lost its edge over every other GNU/Linux distribution (and even FreeBSD/PC-BSD) on this laptop.

I've been sticking with my installs much longer than usual — I'm still using a now-year-old installation of OpenBSD 4.2 on my $15 Laptop (and OpenBSD 4.4 will be released on Nov. 1).

See tomorrow's post for a breakdown on what I'm running on every machine.
