Hi, Thanks for the help. I could install the fix. But, I face memory problem. Though I run very few applications, I see that almost all of my memory is eaten up. Pasted below output of 'top' sorted by memory. Is there a solution for this? top - 23:26:20 up 2 days, 1:59, 4 users, load average: 0.05, 0.06, 0.02 Tasks: 197 total, 2 running, 195 sleeping, 0 stopped, 0 zombie Cpu(s): 1.8%us, 1.8%sy, 0.0%ni, 96.4%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 2039792k total, 1836668k used, 203124k free, 86244k buffers Swap: 2867560k total, 119444k used, 2748116k free, 979172k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 1479 root 20 0 233m 127m 26m S 5 6.4 28:59.93 Xorg 8388 pnagral 20 0 283m 110m 23m S 0 5.6 0:48.48 thunderbird-bin 19311 pnagral 20 0 233m 96m 70m S 0 4.8 0:15.95 soffice.bin 26340 pnagral 20 0 123m 69m 14m S 0 3.5 0:23.77 python 27259 pnagral 20 0 171m 57m 22m S 0 2.9 1:07.18 gnome-do 26024 pnagral 20 0 190m 47m 21m S 0 2.4 0:25.03 chromium-browse 26398 pnagral 20 0 109m 30m 19m S 0 1.5 0:05.12 pidgin 26056 pnagral 21 1 114m 28m 11m S 0 1.4 0:19.43 chromium-browse 2942 pnagral 20 0 149m 27m 15m S 0 1.4 0:20.67 nautilus 8243 pnagral 20 0 33900 25m 8244 S 0 1.3 0:19.87 compiz.real 9958 pnagral 20 0 98.4m 22m 14m S 0 1.2 0:02.64 gedit 27916 pnagral 20 0 92600 22m 15m S 0 1.1 0:00.43 Giver 2268 pnagral 20 0 78864 18m 9940 S 0 0.9 0:10.98 awn-applet 27928 pnagral 20 0 104m 17m 10m S 0 0.9 0:00.23 chromium-browse 2882 pnagral 20 0 88200 17m 9780 S 0 0.9 0:17.00 gnome-panel 5928 pnagral 20 0 34128 16m 9604 S 0 0.9 0:00.12 python 3046 pnagral 20 0 174m 16m 13m S 0 0.8 0:18.53 nm-applet 3022 pnagral 20 0 73044 15m 8412 S 0 0.8 0:01.82 python 18911 pnagral 20 0 72280 13m 9m S 2 0.7 0:03.77 gnome-terminal 8245 pnagral 20 0 60988 11m 8964 S 0 0.6 0:04.09 gtk-window-deco 2784 pnagral 20 0 61564 9904 6068 S 0 0.5 0:12.43 notify-osd 26027 pnagral 20 0 66428 8900 6936 S 0 0.4 0:00.02 chromium-browse 3024 pnagral 20 0 77044 8824 6572 S 0 0.4 0:00.53 bluetooth-apple 3017 pnagral 20 0 60728 8424 6052 S 0 0.4 0:04.07 update-notifier 2984 pnagral 20 0 136m 8032 5880 S 0 0.4 0:05.97 gnome-power-man 5824 pnagral 20 0 67604 7900 5640 S 0 0.4 0:08.33 avant-window-na 3019 pnagral 20 0 72952 7532 4456 S 0 0.4 0:00.66 fusion-icon 2698 pnagral 20 0 144m 6872 4456 S 0 0.3 0:10.35 gnome-settings- 3443 pnagral 20 0 64516 6160 4236 S 0 0.3 0:27.31 cpufreq-applet 27097 root 20 0 9320 5984 2692 S 0 0.3 0:00.04 python 2977 pnagral 20 0 123m 5140 3396 S 0 0.3 0:00.37 gnome-volume-co pnagral@pnagral-ubuntu:~$
