dgw's questions

When I go to the Desktop and click on a media icon (for my flash drive, a CD, whatever it is), the following problems occur, in this approximate sequence:

• Nautilus will close if it's open.
• the desktop icons disappear
• my Window List shows a button that says "Starting File Manager"
• the icons reappear
• the button in Window List disappears

Because of this problem, I can no longer drag and drop media, nor can I right-click to perform actions such as "Eject" and "Safely Remove Drive".

The same symptoms occur if I click a media icon (that is also present on the desktop) in Nautilus' Computer view, though notably not if I click in the places list on the left.

I have confirmed that this problem happens only if there is a CD in the drive (Matshita UJDA360).

Also, inserting a disc into the CD drive appears to kill all running programs and restart Nautilus (or X; I'm not sure). Applications like Brasero and Rhythmbox will not start while there is a disc in the drive. Removing the disc doesn't result in the list of media updating; it must be forced to update by clicking on one of the desktop icons and going through one of the above-described cycles.

It doesn't seem to matter what type of disc is in the drive. This has happened with CD-RWs I burned years ago using Roxio on Windows XP, the Ubuntu disc I installed from (burned with InfraRecorder Portable under Windows XP), and the retail game disc for Star Trek Armada II.

The first indication of a problem was Brasero dying when I tried to insert a disc for erasure and rewriting. Since then, I've drafted several different questions on various issues, finally combining them into this one when I realized that having a CD in the drive was the common link.

Could this be a simple driver issue? If Ubuntu is dynamically detecting my hardware on boot, can I specify drivers for devices that I know will be a problem if the default files are used?

I'm beginning to think that my laptop, an old Dell Inspiron 2650, is just too old or proprietary-driver-hungry (or something, maybe RAM-starved) for Ubuntu and Windows XP to play nicely alongside each other. Or maybe I just need to carefully take my wall-wart machine to a coffee shop for an afternoon so I can download updates and such from the Internet, as I lack a home connection.

I have a Dell Inspiron 2650 (with NVidia graphics, using nouveau drivers) that I'm using to try out Ubuntu. It's all great, except that Hibernate and Suspend aren't usable.

Yes, I know that questions about power-save issues are rampant in the Linux support universe, but it seems that every time I find a solution it's for a very specific hardware combination and doesn't apply to me. So anyway, here goes.

When I resume from either power-saving mode, I'll get graphics problems anywhere on the range from a few scattered random-colored pixels that won't change; all the way to full-screen patterns that don't change as I move the mouse, hit keys on the keyboard, or even bring up the shutdown dialog using the power button.

Those full-screen issues (which may involve stripes with random pixels, partial black screen, or both) always end in me forcing the machine to shut down by holding the power button.

I haven't done much testing yet to determine what severity level is most commonly associated with each mode, but I do avoid using either power-save option because of these issues.

I'll add info on my hardware as I can gather it (no home internet connection, and this laptop is tethered to my desk by a dead battery and casing degradation). Please feel free to request something specific in the question comments.

Hardware Info

See this hardinfo report for my system's hardware configuration. (No, my username is not "myuser"; I sanitized hardinfo's output before publishing it.)

Screenshots

These screenshots are from a relatively mild occurrence, which happened after the second hibernation I took that session. The first one worked great, though I used the wireless card and Firefox heavily between the two hibernation attempts.

Take a look at what happened when I opened my home directory in Nautilus and scrolled it:

See below for the situations I've tested so far. The real trouble comes when the machine resumes to an unusable state; in such cases I can't even unlock the screen or properly reboot, much less take a screenshot. I have a hunch that putting a CD in the drive will cause such major failures, and I will try that at some point; see related question.

Situations Tested

Maverick (10.10)

• Seems to suspend nicely with nothing running
• Seems to suspend nicely with flash drive plugged in
• On resume from suspend with no flash drive, Terminal and gedit running: Funky graphics on top of log output, then blank screen with pixelated cursor; no response to power button (normally will shutdown 60 seconds later)

• Seems to hibernate nicely with nothing running
• Seems to hibernate nicely with a few apps (Terminal, Mouse preferences) running
• Seems to not hibernate when flash drive plugged in
• Seems to not hibernate when System Monitor is running
• Have encountered failed hibernation (after several hours and one successful hibernate/thaw cycle) with no external media connected and no programs running except normal background stuff

Natty LiveCD (11.04_2010-12-22)

When I tested it, Natty wouldn't stay logged in. It played part of the login sound and then [ OK ] appeared in the top right corner (white-on-black terminal text) for a few seconds. Then it kicked me back to the Unlock screen. It did that four times before I gave up and just tested suspend from the Unlock screen.

• Resumed to vertical gray and black lines 2px (?) wide, then shifted to vertical "jail bars" of black over a black screen with above-described random pixels and mouse pointer. No apparent response to input from mouse (clicking randomly). Keyboard and touchpad unrecognized.
