Hello againdunno if this is the right place to post, btw this is mainly something x-related...
and yes, there is another post about "sisusb" (a.k.a. usb-to-vga device) and i'm the same poster, but
1) this is a slight different issue and
2) i need an help
(how strange...
)i need to connect a second monitor (third, fourth...) into my dsl-n system using sisusb
sisusb, aka usb-to-vga device, is an usb device with a vga connector, you plug the monitor into vga connector, and device into usb port "et voila" monitor plugged to vga...
i know this device and this monitor are working 'cause they work if plugged into a fedora system
i had to compile (using knoppix 4 dvd like someone adviced me) sisusb.ko module
then copied into dsl-n system.
then i did load module (with "insmod /home/dsl/sisusbvga/sisusb.ko". and added into /opt/bootlocal.sh so i know dsl load it every start)
then copied sisusb_drv.o into /usr/X11R6/.../drivers/ directory
then i plugged sisusb into system
and apparently sisusb work: monitor turn on (but show a blank screen with red border: i need to configure it)
i tried to configure it (cut&paste from fedora's configuration) but does not work: system show only one screen
working both on my dsl machine (where sisusb does not work) and on my fedora machine (where sisusb work) i tried to force using "only the sisusb-ed screen"
while fedora-machine start x normally (just, i see it on sisusbed monitor), dsl-n-machine does not work:
| Code Sample |
| # cat /var/log/XFree86.0.log | grep EE (EE) No devices detected. |
so i suppose there is something else i need to do to force dsl-n machine "see" the sisusb??
someone adviced me "modprobe sisusbvga" but report
| Code Sample |
| # modprobe sisusbvga FATAL: Module sisusbvga not found. |
as i previously stated, i already gave "insmod" command (and put it into bootlocal.sh script so i'm sure will be executed at startup).
same result using both XFree86 and Xorg72
so, again, what can i do to force system to "see" the sisusb???
Edit
i add my dmesg:
| Code Sample |
| sisusb: USB2VGA dongle found at address 3 sisusbvga[133]: Allocated 8 output buffers sisusbvga[133]: 8MB 1 ch/1 r SDR SDRAM, bus width 32 usbcore: registered new driver sisusb sisusb: Driver version 0.0.7 sisusb: Copyright (C) 2005 Thomas Winischhofer |

< http://www.webalice.it/dottordivago/appo/lsusb > for lsusb -v (i kept only info on sisusb...)
