Had a frustration with Ubuntu this last weekend. Two glitches, actually. I use my laptop for a lot of stuff, including training presentations. I was doing one presentation to a tiny group using the laptop's LCD directly. Worked marvelously to swap between a powerpoint and VLC. Very slick.
Except one part where a slide on my powerpoint wouldn't display properly in slideshow but would display properly as a preview. Irritating. I'll need to pipe that powerpoint into a proper open format and fix it. Always makes me feel like a boob when my slideshow doesn't synch right.
Then later my tiny group linked up with other tiny groups to make an actual small group. One presenter had a projector, so we wanted to pipe my laptop through his projector since it was my slides that we'd be using for the next two hours.
No dice.
No amount of fiddling that I could figure out in 60 seconds allowed me to pipe data through the external VGA port of my laptop.
Sat down with this at home on Saturday to make it work. Dangit, I'm going to MAKE this work!
Turns out I had the solution in front of me all along. Having previously used EnvgNG to install the latest restricted ATI drivers, the ATI control panel allows me to activate support for a second monitor. At home, plugged into an external monitor, it was detected automagically, greyed out, and merely needed to be activated.
Problem: This procedure requires a REBOOT. No simple alt-F3 screen switching like in XP/Vista.
Okay, so I'm going so solve this permenantly. I'll activate the second monitor, tell it to clone output, and leave it that way whether the monitor is plugged in or not. No dice.
Here, Gateway bites me in the rear. Before I even got around to unplugging the external monitor to find out what happens to the laptop when its told to use an external monitor that doesn't exist (should be "nothing at all", same as turning said monitor off at the switch), I realize that: WHEN DUAL MONITORS ARE ACTIVATED, WIRELESS IS DE-ACTIVATED
AAAARGH!
I hate Gateway. This isn't a driver thing. This is a Gateway thing. This is some stupid quirk to the motherboard itself. Previously I'd already learned, under XP, that installing bluetooth drivers for an external USB bluetooth key causes the wireless to become nonfunctional. It will at that point recognise wireless networks, connect to them, but not talk to them. Solved with Ubuntu, of course, now happily mixing bluetooth and wireless. But not mixing dual-monitors with wireless.
