Dell Desktop Installation Ubuntu 16.04 considerations (Alienware R6)

Before the Asus notebook successfully installed the dual system win + Ubuntu Kylin 16.04, thought it was easy to install on the Dell, the results found that the Dell computer has a lot of pits.

Dell Alienware, GPU 1080Ti, SSD, HDD,UEFI+GPT partition

Follow the installation steps for the problem:

First, FAQ: Install ubuntu Kylin 16.04 64bit, to the Grub interface, click Install, the System black screen

Problem reason: Ubuntu support for NVIDIA graphics card is not good, often appear in dual graphics computer

Workaround: Restart, in the Grub interface, with the mouse to move to the try Ubuntu option, knock E, find quiet splash, quiet splash behind all deleted, modified to quiet splash nomodeset;

(P.S. From here can be seen different brand notebook, desktop settings slightly different, but mainly dual graphics problems, (video card settings, video card disabled issues), there is a screen flash problem, need to disable Ubuntu video driver see previous blog)

Second, Dell problem: When the installation, do not see any mount disk, that is, can only identify the U disk, other hard drive Ubuntu can not see

Problem reason: The SATA set in the Dell computer BIOS is RAID mode, and Ubuntu does not support RAID mode, it needs to be modified to Achi mode, so the problem now becomes how to modify the hard disk mode to Achi without uninstalling Win10.

WORKAROUND: Read CAREFULLY click the open link

First must be determined that there is a WIN10 local administrator account, the general power-on input password is Microsoft and Win10 Sync account, so you check Baidu add a local account and set as an administrator, and then set up in that account, or even if you modify the successful hard drive mode, Also cannot log in Win10;

Then for Win10 to do a repair Disk + data backup, or the system crashes, own responsibility;

Specific steps:

Right-click the Windows Start Menu. Choose Command Prompt (Admin). Type This command and press Enter:bcdedit/set {current} safeboot minimal Restart the computer and ENTER BIOS Setup (the Key to press varies between systems). The change of the SATA operation mode to AHCI from either IDE or RAID (again, the language varies). Save changes and exit Setup and Windows would automatically boot to Safe Mode. Right-click the Windows Start Menu once more. Choose Command Prompt (Admin). Type This command and press Enter:bcdedit/deletevalue {current} safeboot Reboot once more and Windows would automatically Start with AHCI drivers enabled. If the following problem occurs
PS c:\windows\system32> bcdedit/set {current} safeboot minimal
The set command specified is not valid.
Run "bcdedit/?" for command line assistance.
The parameter is incorrect.

Change the above instruction to (by removing "{current}" from the command):
> Bcdedit/set safeboot Minimal
> Bcdedit/deletevalue safeboot

Third, because the video card is 1080Ti, Ubuntu comes with the driver does not support, so the installation process will have resolution problems, the installation interface is too large, do not see the installation of the button, hold down the ALT key with the mouse to drag the window is good;
Four, install Ubuntu reference Click to open the link, there are two points different: 1. Partition, you can set the/,/swap,/boot,/home are primary partitions, because the UEFI system can have many primary partitions, and finally the root directory, that is, the rest of the space allocated/, otherwise the space is wrong size, resulting in space discontinuity will cause a lot of subsequent problems; 2. Finally, EASYBCD is not required, EASYBCD supports MBR partition format, and my computer is UEFI mode +GPT partition (now newer computers are this mode);
At this time for Ubuntu boot, restart after the grub interface to choose to enter the system, uninstall Ubuntu can refer to the previous blog, will not have any impact on WIN10.
After installing Ubuntu, modify the grub file, or the black screen will still appear.

sudo nano/etc/default/grub

Find this line:

grub_cmdline_linux_default= "Quiet Splash"

Revision changed to

grub_cmdline_linux_default= "Quiet Splash Nomodeset"

Seemingly ctrl+o, CTRL +x (see below for details) update grub, typing:

sudo update-grub

Six, the computer restart boot are no problem, but the opportunity to appear, kernel panic-not syncing fatal exception in interrupt, can only be forced to shut down, consulted a lot of problems have said hardware has said software problems, Because you are a new computer so hardware problems, software problems search for a number of possible causes and solutions:
1. Ubuntu Kernel and graphics driver is not compatible, for many Nvidia graphics drivers, support 1080Ti currently has three versions, tried two, not so, so should not be NVIDIA graphics driver problem; 2. For Ubuntu kernel, I initially actually installed the Ubuntu 16.04.02 English version, and updated to the latest kernel 4.8.0, wondering if the kernel is too new (the following description is not). According to a lot of people in the recovery mode into the old kernel version of the system, completely into not go, at the same time, I also uninstalled the current high version of kernel, the result is not to go to the lower version of the login interface loop; and then think of the auto-clean that might have been carried out in accordance with someone else's practice, Upgarde operation, so when you have a stable version do not arbitrarily update the upgrade and clean up the use of software; In addition, I have changed the grub file according to many people, set the default for the low version of kernel, but it is not used, and then see online said there are two grub files ... But I only found a ...
P.S. Found every time the login interface cycle problem, I executed the sudo apt-get upgrade, so try not to upgrade, if there is a circular login problem, can only check Baidu, according to a lot of people's practice, uninstall Nvidia graphics driver, restart, Then can enter the account, but found that the Ubuntu Sidebar Nothing, terminal window can not be moved, reinstall the video card can not display the sidebar, and later found that the system updates the Unity to uninstall, reinstall CCSM, install unity after the good, so learned, Try not to update the system later, update the system will solve some unknown bugs will also bring some new bugs.
3. The problem with the wireless card, the wireless network card of the Dell computer was not Intel (what is called what com), Ubuntu support is not good, but I saw my wireless card is Intel, and UBUNTU15 later also updated; 4. There are some people who have made a system update without kernel panic .... 5. Finally I reload the Ubuntu16.04 kylin,kernel for 4.4.0, then turn off the machine, then kernel panic; 6. Finally resolved, refer to click Open Link, in kernel panic front a few sentences have I2C_DW_ISR in I2c-designware-core, can follow the following modify $ sudo gedit/etc/modprobe.d/blacklist-i 2c-designware-core.conf Copy the following sentence paste in: Install I2c-designware-core/bin/false Restart after the shutdown will not be an error, if there are errors can try to delete files (do a good job)/etc/ Modprobe.d/blacklist-i2c-designware-core.conf (P.S. I do not understand the principle here, only about the opportunity to appear this problem, boot restart are not this problem, so feel very confused, have a clear small partner please message more Exchange)

P.S. Baidu Some of the answers are too old, and no evaluation, each computer parameters are different, not necessarily applicable to their own computers, blindly follow the other way of installation is prone to unclear problems.
