Dell Inspiron 1525 with Ubuntu Comes with 7.10. Upgraded to 8.04. Reported by Bill Kendrick. Linux Users' Group of Davis, July 21, 2008. Purchased June 2008. What worked out of the box: * Wireless & wired ethernet. * Special keys: + LCD backlight brightness controls + Multimedia keys (KDE defaulted to have them control Amarok) + Volume controls (KMix displays its OSD) + "Home" button (I set it up as a shortcut to launch a new Konqueror window) + Battery button (Fn+F3) (KDE brings up battery panel applet pop-up display) * SD memory card reader * DVD drive (only tested reading, not burning) (Had to install standard Ubuntu non-free stuff to watch DVD videos.) * USB (tested mouse, Sprint cellular modem) * Sound (stereo speakers below the LCD -- nice compared to some other laptops!) (Note: Had to use older kernel; see below) Untested: * Modem. * External video: + HDMI + VGA - can't do dual screen + S-Video * Firewire. Problems: * Doesn't switch to X server (VT7) upon resume from hibernation sometimes. Just hit C+A+F7. * Sound doesn't work in 8.04 latest kernel, even after applying modem-driver-related fix from Dell website (tho fix was for original 8.04 kernel). Just booting older kernel (edit /etc/boot/grub/menu.lst and change value of 'default') * 7.10 to 8.04 upgrade dropped Dell repository. Just updated resources (listed on Dell website): deb http://ppa.launchpad.net/dell-team/ubuntu hardy main deb-src http://ppa.launchpad.net/dell-team/ubuntu hardy main * Trackpad annoying to use; no way to disable tap-to-click in KDE under 8.04. Applied some xorg.conf magic I found: Section "InputDevice" Identifier "Synaptics Touchpad" Driver "synaptics" Option "SendCoreEvents" "true" Option "Device" "/dev/psaux" Option "Protocol" "auto-dev" Option "LeftEdge" "130" Option "RightEdge" "840" Option "TopEdge" "130" Option "BottomEdge" "640" Option "FingerLow" "14" Option "FingerHigh" "15" Option "MaxTapTime" "0" Option "MaxTapMove" "110" Option "ClickTime" "0" Option "MaxDoubleTapTime" "100" Option "EmulateMidButtonTime" "75" Option "VertScrollDelta" "20" Option "HorizScrollDelta" "20" Option "MinSpeed" "0.60" Option "MaxSpeed" "1.10" Option "AccelFactor" "0.030" Option "EdgeMotionMinSpeed" "200" Option "EdgeMotionMaxSpeed" "200 Option "UpDownScrolling" "1" Option "CircularScrolling" "1" Option "CircScrollDelta" "0.1" Option "CircScrollTrigger" "2" Option "SHMConfig" "true" Option "Emulate3Buttons" "on" EndSection This also speeds up trackpad _and_ adds circular scrolling support! * Sprint Sierra cellular wireless card didn't work off the bat. Just create /dev/usb/ folder, add symlink to /dev/ttyUSB0 under /dev/usb/. * Suspend seems to lock things up. (I've just been hibernating; my battery's not high-capacity) * Runs hotter than I'm used to from other laptops.
