Thread: Random freeze - Netbook Pavilion DM1-4055EG

hello,
have (had) several problems new hp netbook dm1-4055eg ubuntu 11.10 oneiric ocelot (32 , 64 bit versions)
hardware: amd dual-core e-450 (vison e2) 2x 1,65 ghz / 4 gb ram / 500 gb hdd / 11,6" 29,6 cm brightview led-display 1366x768 / amd radeon hd6310m onboard graphic.

think hardware in pavilion dm1-4000 series same?

first problem bad wifi-connection (wlan chipset bcm 4313). solved using propietary sta-driver broadcom , blacklisting following kernel modules (in /etc/modprobe.de/blacklist.conf):

blacklist brcm80211
blacklist brcmsmac
blacklist brcmfmac
blacklist bcma

second problem fact display started flickering sometimes. looked old cathode ray tube on 60 hz. ugly... came on every session used netbook.
watched days - after time display gets automatically darker or after reactivating (only screensaver - never after suspend). deactivated screensaver , "automatically getting darker function" (sorry - german ubuntu - don't know english expression it). screen doesn't flicker anymore - have swith display off using skript command "xset dpms force off"). moment ok - not perfect.

ok, if someboby has same problems can giving futher information. fight against problems on netbook weeks , tried lot.

1 problem can not solve myselve. netbooks freezes randomly - high workload (extracting rar archives) , watching flash-videos (for example youtube).

@ moment use fbdev (framebuffer) driver graphiccard. seemed little bit better radeon included in oneiric. day netbook frozen several times. no mouse, no keyboard, no buttons - screen (frozen) shown. sound in buffer (last 3-5 seconds) plays in loop. no real advantage radeon.

didn't use proprietary amd driver because driver included in ubuntu-repositorys doesnn't fuction properly. there watermark "not compatible" after activating.

ok, other ubuntu-users netbook or netbooks same chipset ... have same problems? chipset not supported ubuntu? didn't find other problems in forum device.

thanks, marcus

ok, installed fglrx (catalyst) - via dwonload , build amd.com. newest realease. netbook freezes graphics driver. half day ok - frozen. mysterious.

can confirm there no problems chipset? try 1 week win7. annoyance...
