Hi guys I've got a Samsung Q35 - Centrino Duo. Check out my page
does anyone know how to fix that issue?
Yes I posted this advice last week ---> -Andy Hi Mike -I have one of these beasties now, here are some additional notes. I appreciated your original documentation and advise so maybe some of this can help yourself or someone else.
Suspend works most of the time, it requires Ctrl-Alt-F1 and then Ctrl-Alt-F7 to get video back. Hibernate proceeds correctly, but on reboot the hibernation data is ignored and it boots as if from cold.
By default the audio does not work well. There is a high frequency tone while the audio is active and changing mixer settings while audio active destroys audio until next boot. I updated to the latest Alsa drivers, and added the following to /etc/modprobe.conf
options snd-hda-intel index=0 single_cmd=1 model=laptop-eapdOn reboot sound is great. There does not seem to be an internal mic but the external mic jack also works after this. I don't know if the alsa upgrade was necessary because I found this solution after it.
WPA/WPA2 can be made to work using wpa_supplicant. I got it working first by hand, then discovered the wpa_supplicant already existed in FC5 as a service with integration into ifup and ifdown, so chkconfig wpa_supplicant on will help. TKIP support has a problem, I found setting my wireless router to WPA2 AES avoided the problem. Wireless is then very solid.
When setting your WPA key, note you have to encode the key first using wpa_passphrase before sticking it in /etc/wpa_supplicant/wpa_supplicant.conf
wpa-supplicant needs to be told the ipw3945 device is to be communicated with using -D wext protocol.
I can't get NetworkManager to recognize that wlan0 exists as an interface, despite that system-config-networking knows about it.
I killed tap to click on the synaptics touchpad by adding Option "SHMConfig" "yes" Option "MaxTapTime" "0" to the Input Device / Synaptics part of /etc/X11/xorg.confI was only able to get vesa xorg support to work so far, but you can select 1280x800 layout after setting a generic LCD monitor of 1280x800 resolution. This is the main deficit left now, no xv.
In general it was pretty encouraging. The chipset in the laptop is very new but everything works to a greater or lesser extent, most of it to the greater extent. In a way that makes a new rod for Fedora's back because it is so close to perfect that the remaining annoyances are correspondingly more annoying...
