<div class="gmail_quote">i have Dell Xps 15 with config:- 8 Gb RAM 2nd generation i7 processor 2.2 GHz Boost 2.0 upto 3.30 GHz Dual Graphics Card Intel HD 3000 & nvidia geforce GT 540M with Optimus Techonology 720 GB hardisk Motherboard Dell XPS system L502X Intel centrino 6230 Network Card with BT 3.0 I have installed 2 linux distro on my External USB portable seagate 500 GB hardisk fedora 15 & Ubuntu 11.04. i have installed these distro by using HP pavilion dv 2762 tx with config:- Core2duo 1.83Ghz 2Gb ram nvidia geforce 9600m graphics card Both these distro works with all other older laptops Like HP, Dell studio 1 yr old config , Compaq 5 yr old, but not on my Dell XPS 15. To check my laptops hardware compatibility i used a Ubuntu 10.10 live Cd. it works fine . i use this cd as a live media but when i tried same Ubuntu 10.10 on live usb it gives blank screen or error which i mentioned below. To check that my iso file damaged or my download has been corrupted or not, i tried different distros with different desktop enviornment like Gnome,KDE,Xcfe & Lxde. i tried fedora 15, ubuntu 10.10, ubuntu 10.04, ubuntu 11.04. slackware,eduboss each with avail flavors. But all i have tried gives almost same error with each distro. i don't know what is this some kind of bug or lack of support with dell chipset (hardware). if live cd boots well then i think there is nohardware compatibility issue with linux. I think this is lack of usb support because may be Linux has no support until now for latest motherboards or hardware architects. These are the errors i got with different distros. i am not able to figure out what's going on bcz i'm rookie in Linux programming. But if anyone can do it, plz help me i haven't run my linux from previous 1 and half month and i'm a linux addicted. starting from Fedora 15 gnome(almost same for kde except starting numbers) error:- [ 2.571729] [drm:intel_drm_platform_mux_info] *ERROR* MUX INFO CALL FAILED [ 2.571847] [drm:intel_drm_platform_mux_info] *ERROR* MUX INFO CALL FAILED Dropping to debug shell. sh.can't acess tty:job control off dracut:/# Fedora 15 LXDE [ 2.514402] nonveau 0000:01:00.0:invalid ROM contents [ 2.614971] [drm] nonveau 0000:01:00.0:POINTER to BIT load vol table invalid [ 2.639331] [drm] nonveau 0000:01:00.0:0xd518:12cwr fail: -6 [ 2.75332] [drm] nonveau 0000:01:00.0:PGRAPH:unsupported chipset,please report!

The debian live image failed to boot. Please file a bug against the 'live-initramfs' package or email the debian Live mailing list at <<a href="mailto:debian-live@lists.debian.org" target="_blank">debian-live@lists.debian.org</a>> make sure to note the exact version, name and distribution of the image you were attempt to boot. The file /live.log contains same debugging information but booting with debug command line parameter will greatly increase it's verbosity which is extremely useful when diagnosing issues. live-initramfs will start a shell. The error message was: Unable to find a medium containing a live file system. Busy Box v.1.10.2 (Debian 1:1.10.2-2) built in shell (ash) Enter 'help' for a list of built in commands. <bin/sh:can't access tty:job control turned off (initramfs)- Ubuntu 11.04 Gnome Black screen nothing. Ubuntu 10.10 & 10.04 gnome (Both gave same error "Backtrack 5 also" bcz it is ubuntu 10.04 based distro) GLIB_________________________(some kind of error i could note bcz it stays for few seconds) stdin:error0 /init:line7:can't open /dev/sr0:no medium found /init:line7:can't open /dev/sr0:no medium found same error repeating I also tried to check disc for error option but same error as above . Slackware Bcz it's command line it has direct option of installation no live media. I have created live usb using unetbootin latest version. if i get any update regarding problem soon i'll release it's second version. lolz!!! Regards Navdeep Singh </div>
