asi blbost, ale za pokus nic nedas :-) i kdyz v instalaci bylo jiste take pouzite libinput, zkus prehodit na drive pouzivane evdev:Kód: [Vybrat]# v pripade ze NEmas HWE (jadro 4.15)sudo apt purge xserver-xorg-input-libinputsudo apt install xserver-xorg-input-evdev# v pripade ze mas HWE (jadro 4.18)sudo apt purge xserver-xorg-input-libinput-hwe-18.04sudo apt install xserver-xorg-input-evdev-hwe-18.04
v man xrandr u parametru --transform jsou vysvětlené homogenous coordinates --transform a,b,c,d,e,f,g,h,i Specifies a transformation matrix to apply on the output. Automatically a bilinear filter is selected. The mathematical form corresponds to: a b c d e f g h i The transformation is based on homogeneous coordinates. The matrix multiplied by the coordinate vector of a pixel of the output gives the transformed coordinate vector of a pixel in the graphic buffer. More precisely, the vector (x y) of the output pixel is extended to 3 val‐ ues (x y w), with 1 as the w coordinate and multiplied against the matrix. The final device coordinates of the pixel are then calculated with the so-called homogenic division by the transformed w coordinate. In other words, the device coordinates (x' y') of the transformed pixel are: x' = (ax + by + c) / w' and y' = (dx + ey + f) / w' , with w' = (gx + hy + i) . Typically, a and e corresponds to the scaling on the X and Y axes, c and f corresponds to the translation on those axes, and g, h, and i are respectively 0, 0 and 1. The matrix can also be used to express more complex transformations such as keystone correction, or rotation. For a rotation of an angle T, this formula can be used: cos T -sin T 0 sin T cos T 0 0 0 1 As a special argument, instead of passing a matrix, one can pass the string none, in which case the default values are used (a unit matrix without filter).
Pokud stále platí, že při instalaci (liveUSB?) to bylo OK a po instalaci se to rozhodí, tak to musí být jen nějaká ptákovina. IMO by neměl být zásadní problém porovnáním zjistit, co je z live bootu jinak než z nainstalovaného.
[...] ale proste to ignoruje konfiguraci v /usr/share/X11/xorg.conf.d/99-calibration.conf
