1. [LNX]Travis' Linux Lament continues ...
Howdy y'all!
New Linux problem for everyone:
I've been playing with the eu_engin.e include file, to produce graphics in
Linux. I attempted to
run the following short code:
-- Test program to switch graphics mode and draw a yellow circle in Linux.
-- File located at: /home/Travis/Desktop
-- Run from Linux command prompt as root after cd'ing to file location.
include eu_engin.e
if graphics_mode(19) = 1 then
puts(1, "Unable to switch graphics mode!\n")
end if
ellipse(YELLOW, 0, {10, 10}, {20, 20})
sleep(5)
if graphics_mode(-1) then end if
-- end code
When I attempt to run this, no circle appears on the screen and no ex.err file
was produced.
However, upon termination, I found these lines:
Int 0x10 is not in rom (0114:0113)
No VESA bios detected!
Try running vga_reset.
Using VGA driver.
Now then, I know that under DOS, this will run correctly, because I changed
"include eu_engine.e"
to "include graphics.e" and ran it without problems.
In Linux, I could find no documentation, neither in the eu_engin docs or as a
man page, on
vga_reset. I picked mode 19 so that I could use a VGA driver.
Any ideas? Might just be one of those occasions where I have to be smarter than
what I'm working
with.

eu_engin.e uses the shared library svgalib.so. The error you received is =

1) Run as root. If OK, try doing chmod 666 /dev/tty (extend console =
