Display stuck on 640x480 - Ask Ubuntu

i have old hp proliant. i've got dual-boot setup windows 7. windows 7 tells me i've got generic non-pnp monitor on standard vga graphics adapter, , display settings set 1024x768, looks nice.

i've tried xubuntu , lubuntu, can't change monitor settings: it's stuck on 640x480 , large fit on screen.

i've tried nomodeset in grub settings didn't help. i've seen several pieces of advice here, seem deal nvidia adapters. can do? can't use machine this!

it looks fine while installing... splash , information screens correct. it's once wants login display 2 times large screen.

also... seem remember having problem once before pc. of course, have no idea how managed fix it.

i found way fix this:

• 1st install ubuntu 14.04 (i tried using lubuntu , xubuntu). screen display 640x480.
• ignore notifications of new ubuntu versions.
• set "notify me of new ubuntu version" "never" (software & updates)
• from command prompt, run sudo apt-get update sudo apt-get upgrade sudo apt-get dist-upgrade (apt-get-update install necessary display driver)
• reboot: display correct.
• back software & updates: change "notify me of new ubuntu release" "for long-term support versions"
• from command prompt: sudo do-release-upgrade (this took me 2 hours)

my old vga monitor works correctly ubuntu 16.04
