Title: rearrange a piece of guide in tinycore
Post by: vinnie on February 10, 2011, 11:26:43 PM: I found this guide http://forums.debian.net/viewtopic.php?f=7&t=59055 for debian but command dont work.
Code: [Select]
9. Here is a fix for the screen rotate button, Normally the Roate Button is assigned to XScreenSaver (at least in gnome). There is a fix but it is a bit more advanced and I found this in the ubuntu forums posted by a user, Sergey1369 (see notes at bottom for references). Do this as root to be able to map commands to the rotate button: “cd /lib/modules/2.6.35-23-generic/kernel/drivers/platform/x86 cp eeepc-laptop.ko eeepc-laptop.ko.orig sed -e 's!\x1a\x0\x0\x0\x98!\x1a\x0\x0\x0\x99!' eeepc-laptop.ko.orig > eeepc-laptop.ok rmmod eeepc-laptop modprobe eeepc-laptop GOOD: Now button can be binded via standard keyboard shortcuts to any program. BAD: every kernel update requires repeating procedure.” Now create a mapping as user: echo “keycode 161 = XF86Mail” >> ~/.Xmodmap Reboot or restart X-server and you can now map the button in your keyboard shortcuts (like the touchrotate command or compiz expo in my case)
I am interested in this part, you could tell me what differences there are between tinycore and debian to make it work?

I found this guide http://forums.debian.net/viewtopic.php?f=7&t=59055 for debian but command dont work.

This could be due to a couple of things:

1. the debian module is not from the same kernel version as that used by tc and thus could have changed.

2. did you use busybox "sed" or the full version from the "sed" extension? Sometimes the full version will work whereas the busybox version will not.

Post by: curaga on February 11, 2011, 10:46:36 AM: Ugh, a binary hack. That might or might not work.

Anyway, did you gunzip the module before doing that?

Post by: vinnie on February 11, 2011, 11:46:03 AM: Gunzip is installed and working, but I had not unpacked, this time I did.
I also installed sed.tcz for safety

Code: [Select]
root@box:/lib/modules/2.6.33.3-tinycore/kernel/drivers/platform/x86# gunzip eeepc-laptop.ko.gz root@box:/lib/.../x86# cp eeepc-laptop.ko eeepc-laptop.ko.orig root@box:/lib/.../x86# sed -e 's!\x1a\x0\x0\x0\x98!\x1a\x0\x0\x0\x99!' eeepc-laptop.ko.orig > eeepc-laptop.ok ok

Code: [Select]
root@box:/lib/.../x86# rmmod eeepc-laptop rmmod: can't unload 'eeepc_laptop': unknown symbol in module, or unknown parameter This not work, nor therefore modprobe:

Code: [Select]
root@box:/.../x86# modprobe eeepc-laptop modprobe: can't load module eeepc-laptop (kernel/drivers/platform/x86/eeepc-laptop.ko.gz): unknown symbol in module, or unknown parameter
???

Post by: Juanito on February 11, 2011, 01:26:12 PM: does "modinfo eeepc-laptop" show any dependent modules?
Title: Re: rearrange a piece of guide in tinycore
Post by: vinnie on February 11, 2011, 01:36:36 PM: Code: [Select]
root@box:/lib/modules/2.6.33.3-tinycore/kernel/drivers/platform/x86# modinfo eeepc-laptop filename: eeepc-laptop
but I think something is not right because if I try a module at random, I have the same result:
Code: [Select]
root@box:/lib/modules/2.6.33.3-tinycore/kernel/drivers/platform/x86# modinfo supertcpc filename: supertcpc
Title: Re: rearrange a piece of guide in tinycore
Post by: curaga on February 11, 2011, 02:16:14 PM: Last lines of dmesg please. I also recall the eee module depended on some extensions, maybe it was hwmon.
Title: Re: rearrange a piece of guide in tinycore
Post by: tinypoodle on February 11, 2011, 02:25:29 PM: Looks like there might be a typo in those instructions...
Code: [Select]
sed -e 's!\x1a\x0\x0\x0\x98!\x1a\x0\x0\x0\x99!' eeepc-laptop.ko.orig > eeepc-laptop.ok
ko != ok

double entendre intended :P

Ok i correct this passage but i have the same result:
