As some of you may have noticed, I have been posting some questions the last day or so on my troubles moving from 2.4 to 2.6

Here I hope to give some tips to people who were in the same boat as me.

- In order to get your USB mouse working, disable ALL ACPI options in the kernel. I mean *all.* When I had even one enabled, my kernel would stop loading at the point where it tried to get PS/2 going. If it still does not work, try putting 'pci=noacpi' in your boot options.

- Getting terminals like Eterm to load. I made sure to enable UNIXPTY98 support under char. devices, as well as PTY support under psuedo FS, but my Eterm would still quit saying that /dev/pty was not avaliable. The answer is to remerge Eterm.

- Alsa. I had Alsa working in 2.4, but when I went to 2.6, I ran into some problems. Firstly, sound quality was horrendous in xmms/totem. Once again, the answer is to remerge them. However, I still have not been able to figure out how to make my 'amixer set Master 75 unmute' setting to stay after reboots.

Anyway, I hope this helps you people out.

Oh, believe me, I read that (I used it to help move kernels).

I created this as more of a supplement. I thought people would find it more helpful than having to dig through pages of various threads.

I know there is more than one place in the forums that discusses this; there's a command to save your volumes (alsactl store) then recall them (make "alsactl restore" run on startup). This will save you the trouble of having to run alsamixer every reboot.

well ... you should check your machine ... because i have three machines running 2.6, all of them have usb mice and ACPI is infact enabled on all three of them.

well, also no such problems here. i've directly switched from 2.4 to 2.6 on two of the machines (while the third one always runs most recent mm-sources) and i haven't recompiled eterm to get it working. it just works. of course i've enabled UNIX98 PTY support directly as i knew already from the changelog (which is included in your kernel documentation directory) that the redundant functionality in devfs got removed somewhere around 2.5.48. sometimes it really helps reading documentation :)

you should use the alsamixer save/restore functionallity for that. also documented in the alsa docs.

I had the problem about auto setting the sound 2. So I started to read man pages and found out that this is how you can set you mixer

amixer -c 0 sset Master,0 74% unmute
amixer -c 0 sset PCM,0 74% unmute

hope this will help some gentoo users.

I had also Problems with the ACPI Support (kernel stop on boot - ps/2), remove ACPI from the Kernel doesnt helped but now i put append="pci=noacpi" in lilo.conf and the kernel boot!

Thanks to TheWart!

1) My USB keyboard and mouse work just fine with ACPI enabled - I would consider disabling APCI bad advice, even though a slightly broken ACPI went in -test4 or -test5 (can't recall) it should have been backed out in -test6. Disabling useful options are always a last resort.

2) mentioned in the ebuild as a ewarn that you need that - I don't use eterm but GNOME terminal fx. works without remerging.

3) ALSA is inkernel in 2.6, unmerge your ALSA drivers and use the inkernel ones instead - put commands to be run on boot in /etc/init.d/local.start You of course still need alsa-lib and the various tools - but alsa-driver is obsolete with the arrival of 2.5.8 or whenever ALSA went in the kernel.

I had a similar problem with terminals. Even xterm couldn't get a pty. My fix was to disable the /dev/pts extended attributes. What are those supposed to do, anyway?
