bug report

I need some advice on where to send a bug report. Here's what happened: I was accessing an SMB filesystem mounted "mount -t smbfs" when file accesses (things like "ls" and "cd") started producing "Segmentation fault" messages. I looked in my system log and found: Apr 16 16:58:53 pent584 kernel: kernel BUG at dcache.c:128!

Re: [Wlug] 3D and Laptop

by Chris Ogren

I have a Dell 4000 notebook with the Rage128 chipset and 1400x1050 capable display (sxga+??). I have occasioanlly encountered odd behavior of the xserver locking up and the display washing out when I try to logout of Gnome. This behavior does not occur every time though. I think possibly an X server config problem or perhaps I need to install an updated version of XFree86 4.x. Could you post a copy of your X config and XFree86 version? Although I wish I had the nVidia chipset now. Thanks, Chris On Wed, 2002-04-10 at 10:42, Brian J.

If you use QT embedded, which the Zaurus uses, you can compile a native x86 version that will run on X using the frame buffer. Also there are cross compilers that you can compile with so the resulting binaries will run on the arm processor. > > I'd love to get one, especially if I could get NetHack/Zangband to > run on it. ;) I used to have nethack on my iPAQ (don't know now to play, so i uninstalled it, but i did work). --brad > > James > KB1FJQ > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug

I've been wondering how difficult/how much code hacking is needed to compile stuff for it. Is there an emulator or something so I can play with it? I'd love to get one, especially if I could get NetHack/Zangband to run on it. ;) James KB1FJQ

I am going through a back log of emails... the Zaurus (from Sharp) rocks!!! It is a full linux operating system on a hand held device. The number of apps available to it is growing by the day. It has a full keyboard (small but usable) and many other nice features. When you install vnc server on it you can get a really cool window on your desktop to interact with the device.
