That looks better. I was convinced that most kde-3 apps had a xinerama USE flag, hence my 'emerge -e world' comment that Iain picked up on.

Re: [gentoo-user] Kernel crash - howto find out what happened?
2008/10/12 Alexander Puchmayr [EMAIL PROTECTED]: MY gentoo system (an [EMAIL PROTECTED], 2GB ram, nforce4-chipset) worked fine for nearly two years, but now it frequently freezes, sometimes (not always) scrollock and capslock LED blinking). If you have another machine lying around, try setting up netconsole and/or serial console logging. They should catch any dying messages from your kernel. Blinking LEDs indicates a panic, which means you should get a message in those cases, at least. Using serial console is the easiest and most reliable way, but requires a serial cable. Netconsole just uses ethernet but isn't as reliable. Take a look at Documentation/serial-console.txt and Documentation/networking/netconsole.txt under your kernel source directory for more info.

[gentoo-user] nvidia driver 177.80 + xorg 1.5.1 + Compiz
Hi! Somebody out there try to set up the latest xorg server (and all the ~x86 dependency) the latest nvidia driver and compiz? I would like to try, but my latest attempt three weeks ago caused same crazy problems (X didn't start at all), and I am not so crazy to do the same mistake twice in a row, without some prior advices. Well in my latest attempt I used xorg 1.4.2 and 173.14 nvidia drivers (I don't like Marked beta software). Thanks Nicola

[gentoo-user] Easily coping with a domain password
Hi, Some weeks go well, some don't. For me, this one isn't. The AD at work was moaning that I needed to change the password, which I duly did under protest. Then all hell broke loose. 30 seconds later the account was locked. That turned out to be kontact checking Exchange once a minute when I thought I had unset auto checks. Phoned IT, got the account unlocked. And it happened again, this time kwallet had cached something. Fixed by manually going through everything in kwallet, changing all old passwords I found. And I got locked out a third time, which appears to be due to ldap lookups (more than one). $DEITY only knows where these are coming from, I've been doing some experimenting lately IT are getting a wee bit upset with me, and this happens regularly once a month but today was especially bad. Methinks I should consolidate all the many apps and URLs that auth against the domain. And I'm wondering how best to do this as I'm clueless about it actually - I normally avoid MS stuff like the plague. Should I be looking into winbind? Or configure kerberos to join the domain and have all my apps use that? Some ldap-proxy type setup? Pointers to howtos and opinions on what's worth the effort are all that I'm after today - I can read the details in the man pages myself once I have a known direction to follow. If my three ideas above sound stupid, that's because they probably are :-) -- alan dot mckinnon at gmail dot com

FTDI work very well under windows or linux. Once you add the appropriate driver (via the linux kernel) you can boot either winblows or linux and use the 9pin-serial-to-usb as you like with either OS. The device is setup and works (hence the existance of the /dev/ttyUSB0 device). If the driver wasn't setup that device wouldn't be created. It works fine with minicom. Its just not responding in wine or vwmare (when mapped to a windows com port).
