[13:13] <douglas_br> hello all!
[13:17] <douglas_br> we have ltsp clients that not show a good resolution (only 640x480), after help was indicate to install "old" xorg server in ubuntu 18.04 lts to fix (or accept) the resolution at clients. My doubt: installing this pacakge can broke something, or its secure to install it?
[13:18] <tjaalton> what do you mean by old xserver?
[13:19] <douglas_br> that mean that accept old cards to run in 1024x768
[13:19] <douglas_br> video card
[13:20] <tjaalton> no, which version
[13:23] <tjaalton> well?
[13:24] <douglas_br> was indicate to follow: https://wiki.ubuntu.com/Kernel/LTSEnablementStack
[13:24] <tjaalton> anyway, installing a package from an older distro will likely break, yes
[13:24] <tjaalton> and what about that?
[13:25] <douglas_br> that I want if can give me error or broke something
[13:27] <tjaalton> I don't understand
[13:33] <douglas_br> let me tell: there are two clients that maybe do not have support resolution screen (only 640x480), so, was indicate that install follow steps in https://wiki.ubuntu.com/Kernel/LTSEnablementStack that after this, the ltsp client can work fine (1024x768). Is it secure to install package at the server side
[13:34] <tjaalton> but you're saying "install older xserver"
[13:36] <tjaalton> you have two choices; either use the stock one that 18.04(.1) shipped with or use the HWE version from a newer ubuntu release
[13:37] <tjaalton> but more interesting is knowing the display hw, because usually it's the kernel driver that says what resolution to use
[13:37] <tjaalton> so, is it intel or amd or what?
[13:44] <douglas_br> S3 UniChrome Pro
[13:46] <tjaalton> what does 'apt-cache policy xserver-xorg-core' say?
[13:50] <tjaalton> ...
[13:51] <tjaalton> I'm assuming you don't have xserver-xorg-core installed, so you'd need to downgrade to it.. 'apt install xserver-xorg xserver-xorg-video-openchrome' should be a start
[13:52] <tjaalton> that gpu needs -openchrome

[13:54] <douglas_br> nothing
[13:54] <tjaalton> so, roll back to non-hwe X stack
[13:56] <douglas_br> intalling that you tell yeah
