[support-gang] using usb2vga with 11.2.0 and 10.1.3

[Kevin Gordon]

DSD:

Hit a snag on your method below:

Moved the .ko

rebooted

rebooted with USBVGA2 plugged in, booted successfully with no VGA display,
as you predicted

ctl-alt-f2

hit enter to login, gives me the bash # prompt

entering stop prefdm at the prompt does not then return a # prompt, just
shoots a bunch of text console lines, ending with

Starting crond:
[21.486698] input: olpc-kbdshim virtual input as
/devices/virtual/input/input6
[97.220326] dcon_freeze_store: 0

any subsequent input echoes but does nothing, have to power off by the power
button

Any suggestions?



More specific instructions for this:

>
> Boot without USBVGA connector attached. Go to a root terminal and move
> sisusbvga.ko to /root:
> # mv /lib/modules/*/kernel/drivers/usb/misc/sisusbvga/sisusbvga.ko /root
>
> Power off the system, connect USBVGA, boot. It should boot
> successfully, but without any VGA output. Press ctrl+alt+f2 to get to
> a root terminal, and stop X/sugar with:
> # stop prefdm
>
> Now load the sisusbvga driver manually and see if it hangs:
> # insmod /root/sisusbvga.ko
>
> Wait a few seconds, see if the system is hung or if you can still type
> on the console.
>
> If you can still type, unload the module:
> # rmmod sisusbvga
>
> and now try loading/unloading a few more times with a few seconds
> pause between each step.
> # insmod /root/sisusbvga.ko
> ...
> # rmmod sisusbvga
> ...
> # insmod /root/sisusbvga.ko
> ...
> # rmmod sisusbvga
> ...
> etc
>
> The idea is to find out whether the system hang is caused by the
> loading of sisusbvga. It might not hang first time, may require a few
> attempts, hence the repeated loading.
