Kiosk slow to boot

[ajd]

Hi all

I've recently set up porteus kiosk 5.4 on a laptop for my elderly mother (to keep things simple). It's been working great for the most part. However, I have a couple of issues:

1. I would like to disable the touchpad so she doesn't keep accidently touching it - is that possible? I don't want to disable the mouse so I don't think I can use the disable_input_devices parameter. Is there any other way to disable one device? I can't find an option to do it in the BIOS.

2. The kiosk is quite slow to boot up (approx 30 seconds longer than I would expect). I've run a debug and attached the log. It looks like it might be getting stuck in a couple of places but I can't work out how to fix it.

e.g. Between these lines there seems to be a long delay if I'm reading the log correctly (I'm a bit of a noob though)

[ 21.044] (II) RADEON(0): Modeline "1366x768"x0.0 69.30 1366 1398 1430 1486 768 770 774 782 -hsync -vsync (46.6 kHz eP)
[ 44.962] (II) RADEON(0): EDID vendor "LGD", prod id 614

There also seems to be a 5 second delay getting the wifi connection but that may be normal?

kiosk 2023 Feb 27 16:54:59 dhcpcd[1315]: wlan0: probing address 192.168.68.105/24
kiosk 2023 Feb 27 16:55:04 dhcpcd[1315]: wlan0: leased 192.168.68.105 for 7200 seconds

I have tried to search the forums but the search keeps timing out. Not sure if that's me or the forum.

Anyway - I would appreciate any help.

Thanks

Hello AJD,

1) You could use 'run_command=' parameter to disable only the input device of your choice.

Sample for disabling Ilitek mouse:

Code: Select all

run_command=xinput | grep 'ILITEK ILITEK-TP Mouse' | cut -d= -f2 | cut -d[ -f1 | while read line; do xinput --disable $line; done

2) 5 secs for wifi connection is normal.

Your debug log is missing. You may upload it to pastebin.com and link here (remove sensitive data like MACs, wifi scans, etc).

Thanks

Hi

Yes sorry - I realised as I hit submit that I'd forgotten to attach the debug. See below.

That's awesome re the run_command - thanks! I'll look into it.

The debug log should be here:

Your system booted within 20 seconds which is pretty OK result.

However - kernel reported unstable clocksource:

Code: Select all

kiosk 2023 Feb 27 16:54:52 kernel:[    0.897776] tsc: Marking TSC unstable due to clocksource watchdog
kiosk 2023 Feb 27 16:54:52 kernel:[    0.897786] TSC found unstable after boot, most likely due to broken BIOS. Use 'tsc=unstable'.

and it may slow down the system after a while.

Google lists many potential solution:

Please try this parameter:

Code: Select all

kernel_parameters=tsc=unstable

or this one to disable HPET:

Code: Select all

kernel_parameters=hpet=disable

or this one to disable idle states:

Code: Select all

kernel_parameters=intel_idle.max_cstate=7

I have no off hand solution so you need to experiment with kernel flags.

Thanks - I'll give the kernel parameters a go.

It takes over a minute from switching on the laptop to the browser appearing. I've had other distros on there that have booted much faster than that. I'm not saying one minute is unusable - It would just be nice if I could make it a bit quicker.

Don't these two lines suggest it's stuck for about 24 seconds? Or am I reading that incorrectly?

Hey

The disabling of the touchpad worked perfectly! Cheers

I tried each of the kernel parameters but unfortunately none of them improved the boot time.

I'll keep digging.

Thanks
