From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020818 Description of problem: At least on a 15" LCD display at 1600x1200 resolution (which is so high-res it makes everything look more realistic ;), the gdm greeter looks like the type of backlight and LCD problems I've seen on old abused laptops. This realistic simulation of failed hardware scares the hell out of the user until the user logs in and wonders whether the display has really failed, at which point troubleshooting starts... Version-Release number of selected component (if applicable): redhat-artwork 0.36-1 How reproducible: Always Steps to Reproduce: 0. Install (null) (this bug was not present in Limbo or Limbo2). 1. Open your eyes and look at the GDM greeter. 2. Is it live or is it BlueCurve? Try to suppress your fears of the former and log in. 3. Log in, and do stuff to display different patterns on the screen to begin process-of-elimination (to make sure that it's actually broken hardware -> eventually you figure out it's not). I suppose a more efficient (in terms of time and effort) alternative to step 3 would be: 3a. Install onto another system with a CRT display, not an LCD, in which case a pattern like this is far less likely to be failed hardware. I didn't have such a spare system handy though. Actual Results: D---it, the display on my Dell just broke! Oh, wait, I can't see the problem when I log in... hmmm... Expected Results: A greeter that doesn't look make my Inspiron 5000e's display look like that of an abused/old/broken laptop. Additional info: This goes WAY beyond ugly. When you look at this on an LCD, it really looks like a failed LCD. I've seen this type of effect on real failed LCDs. You don't want to know how I'd be reacting if my Inspiron wasn't still under warranty. ;( One of the nice things about Linux is that typical behavior does not look like bad hardware. This kind of thing (commonly occuring misfeature in the software that looks like bad hardware) is what I'd expect from Windows or old MacOS. Heck, getting my ReiserFS partitions trashed on another machine of mine running a non-Red Hat distribution (and thereby losing valuable data which I had not yet backed up) a few months ago was more pleasant than this. :( Thus, I've set the bug's severity to high.
A couple of clarifications: It's possible that the defective LCD displays I saw were on old PC notebooks not PowerBooks, but either way this GDM greeter looks like a bad display. If I'm the only person on this planet who reacts this way, that's fine and I'll live with it. I have difficulty imagining that's the case, though (i.e., I'm afraid that friends will be calling me on the phone about this trying to get support from me, etc.).
FWIW: Seeing a similar pattern at two different resolutions (which is what happens with 8.0 on my Inspiron 5000e -- 800x600 on the installer's splash screen, 1600x1200 on gdm's backdrop) makes it more obvious that it's not hardware.
I think garrett has duly noted this, it's sort of a "would be nice" instead of a bug so I'm not going to keep it open. (bugzilla is more of an engineering task tracker and the engineers can't fix this anyway.)
"Are those bumps supposed to be there? I thought it was supposed to be a flat blue background." That's from a real incident in the last week (with Red Hat 9). Alright, so it took over a year for someone to think this was a sign of something broken. Setting the severity to "High" was clearly an overreaction, then. Anyway, I believe redhat-artwork-0.84-1 fixes this bug, so I'm going to reopen the bug and immediately reclose it as RAWHIDE.
