My screen's colors are inverted? or maybe reduced to only 8 different color?












0














My screen's color on Ubuntu is totally inverted as shown in this image



image



I don't know why it does that, but it occurs at startup of the OS, everything goes from normal colors to kind of inverted colors. I've also tried xcalib -i -a which give me the following : Error - Can't open display



UPDATE : Ok it seems that there is only 8 different color available, i found a program that shows me the colors in the 256-color palette along with their ANSI color code in XTerm/ANSI-compatible terminals with a 256-color palette support. image



UPDATE 2 : Ok I've managed to fix this problem, i don't really know how but i tried install all package that is required by my graphic card AMD Radeon HD 7450 and also package of Mesa3D without really installing them, i probably needed their libs to fix that problems.

  • @DKBose No it doesn't, By the way i've got a Radeon HD 7450 as a graphic card. I'm trying to see if there is any driver problem or anything like that
