 Posted: Mon Jan 19, 2004 9:53 pm Post subject: A couple of laptop issues.... |
 |
|
Well, I just installed Gentoo on my hp ze4430us, and so far it is working fairly well (better overall than Mandrake did at least). However, i have a couple problems....
First is that I can't seem to get sound working. I have the gentoo-dev-sources kernel with alsa support configured in, but i have no sound....
Second, is this synaptics touchpad. The scrolling part doesn't work, and the touchpad is fairly jumpy overall. I found a synaptics driver in portage, but it is "masked," and I can't emerge it.
Third, I can't seem to get access to my Windows filesytem. Mandrake mounted it and put a shortcut to it on the desktop automatically, but when I even click on /dev/hda1, it tells me "permission denied" without even asking for the root password.
Any help would be greatly appreciated  . |

is your user in the "audio"-group? try the command "groups" to test it. if not, use "usermod" to change it. if this doesn't work you could post the output of "ls -l /dev/sound/". is alsa started on boot? just check if one of the files "/etc/runlevels/boot/alsasound" or "/etc/runlevels/default/alsasound" exist.

there is already a synaptics-driver included in xfree. backup your /etc/X11/XF86Config and edit it:
in "module"-section add:
my "inputdevice"-section looks like this. you have to adjust at least "identifier", and i'm not sure if "protocol" and "device" are laptop-specific.
| Code: |
Identifier "Mouse0"
Driver "synaptics"
Option "Protocol" "event"
Option "Device" "/dev/input/event0"
Option "LeftEdge" "1900"
Option "RightEdge" "5400"
Option "BottomEdge" "1800"
Option "TopEdge" "3900"
Option "FingerLow" "25"
Option "FingerHigh" "30"
Option "MaxTapTime" "180"
Option "MaxTapMove" "220"
Option "VertScrollDelta" "100"
Option "MinSpeed" "0.02"
Option "MaxSpeed" "0.18"
Option "AccelFactor" "0.0010"
# Option "Repeater" "/dev/ps2mouse"
# Option "SHMConfig" "on"
Option "ZAxisMapping" "4 5"

does your "/etc/fstab" countain a line
| Code: | | /dev/hda1 /mnt/SOMEWHERE vfat noauto,user 0 0 |
? without this line and "user" users won't be allowed to mount it. did you compile the filesystem "vfat" into your kernel? try "mount /dev/hda1" in a terminal and post the result.

Also, don't forget that all of the alsa channels are muted by default. Emerge alsamixer and use it to unmute them and set the volume if you haven't already. |

These are excellent suggestions. Might I also recommend some diligent searching of the forums, and you'll find some more ideas.

Ok, I have the touchpad working now (thanks for the help), but I'm still having problems with the rest. I tried searching the forums, but most of what I found went right over my head  .
I probably should have said this before, but I get an error message when I start KDE:
Error while initializing the sound driver:
device: default can't be opened for playback (No such device)
Neither /etc/runlevels/boot/alsasound nor /etc/runlevels/default/alsasound exist
ls -l /dev/sound/ gives me:
| Code: | total 0
crw------- 1 andrew audio 14, 1 Jan 1 1970 sequencer
crw------- 1 andrew audio 14, 8 Jan 1 1970 sequencer2
|
As for my Windows partition, I edited my fstab, and mounted my /dev/hda1 at /mnt/windows, but the problem is, I can only access it when I'm root. I tried changing the permissions (by right-clicking and going to properties) but it keeps telling me I can't. |

Here is how my XP partition is listed in my /etc/fstab:
| Code: |
/dev/hda1 /winxp ntfs ro,umask=0 0 0
|
The tricky bit is "umask=0" which permits all users total access; if you want finer permissions, set the umask value to something else (in octal). This will work for FAT-like filesystems as well.
Concerning ALSA, have you included support for your sound chipset? Here is my /dev/snd (ALSA native devices):
| Code: |
18:53:30 > ls -alF /dev/snd
total 0
drwxr-xr-x 1 root root 0 Dec 31 1969 ./
drwxr-xr-x 1 root root 0 Dec 31 1969 ../
crw-rw---- 1 root audio 116, 0 Dec 31 1969 controlC0
crw-rw---- 1 root audio 116, 24 Dec 31 1969 pcmC0D0c
crw-rw---- 1 root audio 116, 16 Dec 31 1969 pcmC0D0p
crw-rw---- 1 root audio 116, 25 Dec 31 1969 pcmC0D1c
crw-rw---- 1 root audio 116, 1 Dec 31 1969 seq
crw-rw---- 1 root audio 116, 33 Dec 31 1969 timer
18:53:38 >
|
And my /dev/sound (OSS emulation devices):
| Code: |
18:53:38 > ls -alF /dev/sound/
total 0
drwxr-xr-x 1 root root 0 Dec 31 1969 ./
drwxr-xr-x 1 root root 0 Dec 31 1969 ../
crw-rw---- 1 root audio 14, 12 Dec 31 1969 adsp
crw-rw---- 1 root audio 14, 4 Dec 31 1969 audio
crw-rw---- 1 root audio 14, 3 Dec 31 1969 dsp
crw-rw---- 1 root audio 14, 0 Dec 31 1969 mixer
crw-rw---- 1 root audio 14, 1 Dec 31 1969 sequencer
crw-rw---- 1 root audio 14, 8 Dec 31 1969 sequencer2
18:54:27 >
|
You need the "pcmC0D0p" device for ALSA-native playback, and "dsp" for OSS-emulation playback.

Thanks for the help. My windows partition is accessible now. Sound is the only thing left that I can't get working. I have support for my chipset enabled (at least, I'm pretty sure I do). Here is my /dev/snd:
| Code: |
drwxr-xr-x 1 root root 0 Jan 1 1970 ./
drwxr-xr-x 1 root root 0 Jan 1 1970 ../
crw------- 1 andrew audio 116, 0 Jan 1 1970 controlCO
crw------- 1 andrew audio 116, 1 Jan 1 1970 seq
crw------- 1 andrew audio 116, 33 Jan 1 1970 timer

I'm not quite sure what to do.... |

well, "lspci -v" will tell you everything about your PCI devices, including a soundcard.
Are you loading the chipset driver module? I have an Intel 810 motherboard with integrated sound, so the module I load is "snd-intel8x0".

| It's an ALi Corporation M5451. I've got support for that configured in the kernel, do I have to do something else? I'm not really sure how to load a module... |

If it's compiled as a module (and you're using ALSA), you'll have to "modprobe snd-ali5451". If you're using OSS, maybe it's "modprobe ali5451" ...

| I just rebooted, and it didn't work. I did "modprobe snd-ali5451" again, and it worked, but will i have to type that every time? Isn't there a way to autoload it or something? |

Just put an entry for it into /etc/modules.autoload.d/kernel-2.6 to have it automatically load on boot:

| Thsnks, you've been a big help. Nearly everything (minus the modem but I don't need that) is working now. |
