Hi Aditya and Thomas, Following the hint given by Thomas about fixing the behaviour of the visual counter in the simpleslides module, I tried all the possible styles and found that once the PageNumber is changed into RealPageNumber in the s-simpleslides-*.tex style files. All the styles work fine unless three of them which I describe below. I don’t know how the modules are maintained on the wiki or elsewhere, but if you wish I can send you privately the files where I have changed PageNumber to RealPageNumber so that the simpleslides module can be used ot of the box with LMTX. Best regards: Otared PS: Here are the issues with the three styles which don’t work properly: • BigNumber: for the style to be typeset, one has to modify the part where BigNumberFont is defined %\beginOLDTEX %\loadmapfile[qhv-ec.map] %\definefontsynonym [BigNumberFont] [ec-qhvb] %\endOLDTEX % %\beginXETEX %\loadmapfile[qhv-ec.map] %\definefontsynonym [BigNumberFont] [ec-qhvb] %\endXETEX % %\beginLUATEX \definefontsynonym [BigNumberFont] [name:texgyreherosbold] %\endLUATEX Then the file « example.tex » can be typeset, but the big numbers shown are always 1. • Embossed: for the style to be typeset, one has to modify the part where EmbossedFont is defined %\beginOLDTEX %\loadmapfile[qhv-ec.map] %\definefontsynonym [Embossed] [ec-qhvb] %\endOLDTEX % %\beginXETEX %\loadmapfile[qhv-ec.map] %\definefontsynonym [Embossed] [ec-qhvb] %\endXETEX % %\beginLUATEX \definefontsynonym [Embossed] [name:texgyreherosbold] %\endLUATEX • SideToc: the file example.tex can be typeset with this style, but all pages come out in black… the text cannot be seen.
