Is there such a thing as > operating the screen clearly at anything but the max 1050X1400 > resolution? Thanks. I also have a T30 with the hi-res display. I think it's great! But I can believe that the fonts may be kinda small at that resolution. I like them for most things, but I often increase my XEmacs font size to 14 to make it easier to read. I think that's the only solution, really. Most X apps allow you to choose fonts, including the gnome terminal. select a font you like. The one place you might be struck is the web browser. Some pages built with FrontPage have a problem with the fonts displayed by any browser other than Explorer. This is actually a Microsoft bug in FP that is fixed by a deliberate "fix" in Explorer. But other browsers follow proper HTML and display itsy-bitsy fonts. There is no fix for this. One work-around would be to define several display modes in your XF86Config file. I define 1400x1050, 1280x1024, 1024x768, and 800x600. You can switch "on the fly" by typing or . This is complicated a bit on a laptop in that you don't have a keypad. You need to enable NumLock to place the on the '?' key and the is on the ';' key. NumLock is usually activated on the T30 with , but I found my default X keymap did not allow this, so I had to enter the command: xmodmap -e "keycode 78 = Scroll_Lock NumLock" to set it up to match the markings.

It does all the primitives tasks for the toolkit, things like event handling/filtering, timeouts, input/signal/resource management, basic window geometry handling, etc. Unfortunately there aren't too many toolkits based on Xt, basically Motif and Xaw.

Since I am working alone on it (mostly in my free time), there aren't too many improvements because I am only working in the Text widget and xedit. But anybody is free to help. There is a really large amount of things to be done, from simple tasks like optimization and bug hunting, to some complex tasks like making Xaw multi-thread safe or fully internationalized.

You could write a flasher, but it would probably ruin them much of the time. If this is a common problem, I'd expect google to have some answers.

There haven't been any known bugs in XAA in a long time. I'm not sure we have any compatibility rules for anything other than driver interfaces. XAA interacts with more than the driver, it interacts with other modules and the core server. There may be some explicit assumptions that you are not mixing core modules. Precautions have not been made to allow mixing of an XAA module with a server of a different vintage. As for drivers, you can use a driver older than the server and it will generally work. You can use a driver newer than the server only if the driver doesn't use any entry points or exports newer than the server, and even if that part is safe you usually need to pass the -ignoreABI flag. But I don't think we have any goals of binary compability between core modules. Mark. ___ Xpert mailing list [EMAIL PROTECTED] http://XFree86.Org/mailman/listinfo/xpert

The card needs an interrupt for graphics mode. Does one show up in /proc/pci? If it doesn't have one, that would be a motherboard bios bug. Perhaps there's a newer bios available for it?

In my BIOS, there is an option to choose "first boot video" (or similar). I choose "PCI" instead of "AGP" to post on my pci video card. As a matter of fact, most of the time it takes a few reboot before it posts on PCI.
