Troubleshooting while run Ubuntu 18.08 in Aspire-A715-71G-796T

Calcio · May 2018

Hi everyone. How it's going?

I'm trying run a Live-USB Ubuntu 18.08 in Aspire-A715-71G-796T but after booting Touch-pad, keyboard or USB mouse doesn't works. I can move the mouse pointer but I can't click. When I try boot with a external HDD it freeze on booting.

Someone face the same problem?

I'd recommended trying to dual boot something like the Mint version which should auto-install everything you'll need. And a pretty decent Mint user commununity. Jack E/NJ
UBUNTU MINT
( 0) Pre-shrink Windows partition to desired unallocated space for Linux installation. Shrink it a lot if you want
( 1) Make bootable GPT/FAT32(default) stick from the Linux installation iso with Rufus, a freeware download.
( 2) Set BIOS supervisor password(SECURITY), disable secure boot(BOOT)& enable F12 Windows boot mgr (MAIN). Save BIOS settings & exit. May not be needed with some Linux installations like Mint.
( 3) Shutdown & insert bootable Linux stick
( 4) Turn back on while immediately tapping F12. Select Linux stick to run.
( 5) Preferrably select a default Linux install option
( 6) Follow on-screen instructions to install alongside Windows.
( 7) Let Linux automatically set & resize partitions for Linux & its swap. Adjust for more or less space only if absolutely necessary.
( 8) Shutdown & remove Linux stick.
( 9) Turn back on while tapping F2.
(10) Re-enable secure boot(BOOT) & select UEFI file as trusted(MAIN). Select HDD0, SSD0 or eMMC0, then <EFI>, then <ubuntu>, then grubx64.efi the UEFI file. Enter grubx64.efi in the space provided if selecting it doesn't automatically enter it. Save BIOS setting and exit.
(11) Boot into Windows. Then shutdown again.
(12) Turn back on while tapping F12.
(13) If desired, put grubx64.efi ahead of Windows boot manager in UEFI bootstrapper

Thanks @JackE, I'm trying now to create a live-usb with Rufus, but I don't know if it will solve the keyboard and mouse problem.

A keyboard problem would be rare for a live ubuntu stick. Did you perhaps change the BIOS to legacy mode? Can't do that. Must be UEFI and the live stick must be GPT partitioned. Jack E/NJ

Yeah, I was trying with legacy mode (because without it always Win starts).

I'll try a new boot now.

I think you'll also have to add the grub efi file as trusted in the BIOS in order to get the stick to boot instead of Windows. Jack E/NJ

Do you think the problem is the grub? Because the SO starts, just don't work keyboard and mouse.
I spent all my afternoon trying different approaches to solve it, but nothing.

I don't know why it's happen. It never happen to me in 10 years using Linux.

>>>Do you think the problem is the grub?>>>

No. I think the issue is related to the fact that you're using live USB Linux on an MBR partitioned stick with a Legacy BIOS. The stick should be GPT partitioned with a UEFI bootstrapper, not Legacy BIOS. However, to rule out (or rule in) a hardware problem, does the keyboard seem to work OK if you F2 into and navigate around the BIOS menu? And if you change from Legacy BIOS to UEFI bootstrapper, does the keyboard and touchpad seem to work OK in Windows? Jack E/NJ

I know it (now) Lol.
My Live USB is already use GPT to UEFI (I did it using Rufus).

The keyboard and mouse works fine in BIOS menu and Windows, but not work when I boot using Live USB.

Other information is in BIOS is factory default.

JackE · May 2018

OK, your keyboard, touchpad and BIOS default all seem fine. So live stick itself must not even be loading the keyboard driver which is pretty fundamental. If you're determined to run a live stick instead of dual boot, all I can suggest is to see if a USB keyboard will work so that you can modify the boot stick to load the KB driver. Or post your KB & touchpad dilemma on the Ubuntu forums because this is a fairly unusual problem and it may be something very simple that we're overlooking. Jack E/NJ

I'll try another keyboard. And I'll try update the BIOS too.

I tried the same ISO using Virtual-box and everything works fine.

Thanks for your help and patience.

The VM should be working under the vanilla Windows drivers. Updating the BIOS is NOT recommended due to the risk of brickin even when done inside Windows. It's much too risky for this particularly mundane live stick KB issue. Jack E/NJ
